Passing the torch

BY BENNETT ROLAN |

“One generation commends your works to another,
they tell of your mighty acts.” – Psalm 145:4

G od gifted John Humphrey Amuasi with a passionate mind.  

As a medical physicist, John’s research achievements are vast, and his accolades are many. But John is driven by more than professional success. His heart for the Lord compels him to advance the gospel of Christ while pursuing his research for the prevention, diagnosis and treatment of diseases. 

Before John became a celebrated medical physicist or a beloved BSF board member, he was a young Christian who learned from a mature generation of believers.  

“Challenges are what make life interesting, and overcoming them is what makes life meaningful. The great mentoring I personally received from my supervisors was an example for me to follow,” John said. “I need God’s grace to practice living for Jesus with a willing heart in the workplace as well as in the church, (knowing) that Jesus is with me and watching everything.” 

Growing up in Ghana, John seized every opportunity to pursue his passion. The path took him around the world and allowed him to collaborate with the pre-eminent medical physicists of his generation. John has served more than 40 years on the Ghana Atomic Energy Commission, where he was dean of the School of Nuclear Sciences, and as an expert and consultant for the International Atomic Energy Agency. 

His work included tumor detection and treatment using imaging technologies (CT, SPECT, PET and MRI). Among his most highly regarded achievements was helping establish the first two National Radiotherapy and Nuclear Medicine Centers in the two major cities in Ghana Accra and Kumasi to “manage the menace of cancer in the West African sub-region.” 

A heart for Christ

Early in his career, John’s wife, Joyce, was invited to participate in a Bible Study Fellowship prayer group. In 1990, the group established an Evening Women’s Class, and John saw God working firsthand through BSF. He soon joined a men’s prayer group, which evolved into an Evening Men’s Class, where John served as a substitute teaching leader.  

Over the years, John has served in various BSF roles, including his position on the board of directors, from which he is retiring after 12 years of service. When asked about his BSF experience, John immediately turns the conversation to God’s Word and BSF’s focus to magnify God and mature His people. 

“God has used BSF to deepen my relationship with Him and to strengthen (my) outreach work,” he said. I must say my commitment to BSF work has impacted every aspect of my secular work.” 

Creating a legacy

This is evident through John’s deep conviction to equip the next generation of physicists. In fact, John regards his mentoring work as one of the greatest blessings in his career. 

Citing the priest Jehoida, a little-known character in 2 Chronicles, John views biblical mentoring as a responsibility with far-reaching impact. 

In 2 Chronicles 24:1-2, Jehoida provided wise counsel to the 7-year-old king Joash, and “Joash did what was right in the eyes of the Lord all the years Jehoida the priest instructed him.” 

Through Jehoida’s guidance, the young king restored God’s temple and directed His people to right worship. At the end of Jehoida’s life, the prophet received the great honor of being “buried with the kings in the City of David, because of the good he had done in Israel for God and His temple” (2 Chronicles 24:16). 

“What good did Jehoiada do? He passionately mentored 7-year-old king Joash until he became a great king,” John said. “It is said that the Christian youth (the next generation) is the backbone of the Church. I believe this backbone can be strengthened through mentorship to make the next generation more effective in every respect.” 

As a young man, John learned from mentors in both his profession and his church. They were men who helped guide and counsel him through the challenges of work, life and faith. Today, John is filling that role for several young physicists, along with many others through church and BSF. 

“I am always challenged by Jesus’ statement in Luke 12:48b: “From everyone who has been given much, much will be demanded; and from the one who has been entrusted with much, much more will be asked,” John quoted. “On my return to Ghana, I soon realized that much had been given me, and so I needed to commit myself to serving my Lord and my nation. I asked for God’s grace, guidance and enablement to fulfill every demand, including mentorship.” 

Though challenging at first, John stepped into his mentoring role with a sense of humility and compassion, recognizing that true wise counsel comes from God alone. 

“Having someone in our lives to guide us toward faith and Christlikeness can be good and helpful,” John shared. “Even better is getting to know the Lord ourselves and learning to rely on the Holy Spirit to be our guide. That is making our faith personal. So it is with any type of mentorship. The mentor’s goal is to assist and guide his mentee to excel and become relevant in their chosen profession, be it sacred or secular, like the medical physics profession.” 

Like Jehoida, whose wise counsel impacted the Jewish nation, John’s mentoring work is making a significant difference in the medical physics field. 

One of John's mentees shared:

“Prof. John Amuasi’s mentorship style transcends academics. He affects the religious and moral lives of his mentees, as well. He has always provided wise counsel, which has shaped my personal and moral life as a husband and father of two. Not only his words of inspiration and encouragement make him a great mentor, (but also) Prof. Amuasi’s personal lifestyle is one big example that many young colleagues, like myself, have always admired. He always brings his mentees closer to know God and to live exemplary lives. This has resulted in him producing many great personalities who occupy great positions.”

This mentee’s doctoral research thesis won prestigious such awards as Best Poster Presentation Award at the Maiden University of Ghana Doctoral Conference in 2015 and the world’s Young Scientist Award by the International Union of Pure and Applied Physics (IUPAP) and the International Organization for Medical Physics (IOMP) in 2016.

Taking action

As believers, we have the unique opportunity to influence the next generation for Christ. Whether we serve in the children’s program at BSF, build relationships in the workplace or pour into younger BSF group members, God can use each of us to spread His wisdom from one generation to the next. 

Would you take a moment to pray about how God might want to use you in this way? Together, like John Amuasi, we can offer truth and encouragement to a lost world, one life at a time.

    Nuclear scientist of his country yet humbled himself to be a STL “John has a heart of Jesus” I wish him good health and God’s wisdom to continue mentoring the young next generation. I shall always quote John as exemplary Child of God leading others to God

  4. I was already in a women’s bible study when a friend began telling me about BSF. I didn’t know what it was. The more time we spent together and she talked about it, the more I wanted to be a part of it. She was so passionate when she spoke. I knew her well enough that if she was this excited and committed than I wanted to see what this was all about.

    I pulled into the parking lot on the first night as a visitor and I saw a sea of women and children flowing into the church. As I started walking towards the church I felt the Lord speaking and I hadn’t even hit the door yet! When I left that evening I knew it was God’s plan for me to be here and I was finally where I belonged.
    BSF is life changing!

  5. Your blog reminds me of the importance of training the next generation. After attending a BSF seminar, “Serving the Church” I was inspired to complete my doctorate in Christian Education. My major writing project was The Importance of Mentoring Others for the Continuance of Faithful Ministry in the Church.””

    • I’ve been in BSF for 22 years and it has brought me through rough times. But has allowed me to soar like an eagle. It has given me knowledge through studying the word of God. Gave me knowledge in raising our son and helping my wife who has some difficulties at this time. We praise God each day.
      Thank God and BSF

  6. The story of John Humphrey Amusi is one of God using this spiritual father to effect and inspire a community and the world. There no limit to what Christ can do through men and women leaders who are willing to be leaders for His sake.
    We all have heard that children spell love – T. I. M. E., I am grateful to read John investing his generous heart to glorify God intentionally with mentoring in mind.
    May our Lord continue to bless you and keep you & your work, John.

  16. What a testimony! What a challenge! May my life count for eternity. Thank you John for giving your life to serve the Kingdom of God.

    • Whenever I remember about the time I first encountered the Word of God and the time I came into personal relationship with Jesus Christ I feel good.In lower primary classes, I joined standard one under management of Presbyterian Church.I had not enjoyed the privilege to be brought up in a Christian home,receiving the necessary Christian education. But I was eager to register for a catechism class to be baptized in 1966.After baptismal I was confirmed later the same year and subsequently in high school I was reconfirmed by Rev.Welch in 1972 when I joined Christian Union.I am an ardent believer once you place Jesus Christ in centre of your life all others things follow in place.This involves calling God every day in prayers,pouring our hearts on what we believe,how the believe and how we behave.There is no iota of doubt that rebellion against Jesus salvation bring bad consequences and every thing else out of control.As Christian then is some one who is personally and decisively committed to JC as his saviour and Lord.My conversion was not an instant act, but a long jarneny including forty years in insurance professional industry to which I have a testimony.God is master of our time and destiny, on 18/02/2009 I proclaimed the Lord as the saviour of my life.The mission of God in the world is to reach and deal with peoples,spiritual and physical needs.As I conclude I thank John Amuasia as well as BSFers fraternity for John’s testimony.I am not only encouraged but deeply inspired to enhance my relationship with my Lord Jesus.For only in Jesus one can live a new quality of life.Our prayers continue to glory of Lord.

  17. Here is a man that God has used, and continues to use, to fulfill the Great Commission. John Humphrey Amuasi is the embodyment of the luminaries who Paul is speaking to in Philippians 2:14-15. By the actions displayed in living his life, John illumines the Savior to those around him as well as to those with whom he collaborates around the world. Thank you, John, and praise ABBA, Savior and Holy Spirit, from whom all blessings come. BTW, the Lord’s luminaries are never in an “OFF” position.

  18. We thank God for the life of Brother John.He can rightly be described as a man after God,s own heart.I and my son Kweku have been impacted greatly by his infectious zeal for the Lord which he has alwa ys acted out in true humility.His dear wife Aunty Joyce has always played a very supportive role which is worth emulating.We are very proud of you Brother John and Aunty Joyce.To God be the glory,great things He has done.

  19. A BSF member since 1999. A childrens leader at BSF for 15 years. Loving every minute, blessed immensely. Still a member at BSF but retired as a childrens leader. At 76 yrs old hard to be on the floor. Im now involved with CEF (Childrens Evangelism Fellowship or Good News Club) an after school program in public schools. This is my passion. Love being with older kids and blessed to see them worshipping the Lord and loving Him as they do. See many accepting their Lord and Savior. Thankful to my Lord for choosing me to share the gospel with the next generation. Blessed

  20. What an inspiration and an encouragement for all of us, and for me, personally as a Senior High School teacher in Thailand. Indeed, God’s grace and love alone compel us to show the world that we truly care for others beyond degrees of human limitations. May we continue to succumb to the challenge of effectively and joyfully passing on the torch to the next generation, by influencing others to see and experience Christ.

  21. Dr. John thank you and God bless you for giving your life to serve, teach and mentor others to believe come and follow Christ. Your story is definitely very inspiring for me to do the same.

    • Praise God for Dr.John and his devotion to Christ. Yes BSF is life changing. Fortunately BSF started online. We don’t have a class here otherwise. Revelation of the Word and my wanting to commit and obey is not easy but I’m trying my best. I thank and pray for my sister who introduced BSF into my life. Need my children and husband search and find Him too.
      May God bless you Dr.
      John. May God continue to strengthen you to do his work. Amen.

  22. Dr. John, your testimony is much like Christ’s disciples who shared their whole life. Thank you for your serve to the Lord and His people and for those who are to come through your witness.

  23. I’m so happy to see this testimony about John. As a young boy just out of High School I had the privilege to be driven by him to BSF class every Monday evening. Those Bible Studies made a deep impact in my life which is evident to this day. May God continue to bless him

  24. What a great testimony you have! Your dependence on our Lord Jesus is so obvious. Passing on wisdom from Christ to the next generation whether in our professional or spiritual lives is what we should aspire to accomplish. Thank you For sharing your story

    • Thank you. How real and living God is for all generations that’s what am experiencing in BSF. A good learning for myself n mentoring youngers to depend and trust in the gracious guidance of the Holy Spirit.

  25. Giving honor to God for all that he has done. Sharing the word of God is truely a blessing. As the scripture reminds us, we should study to show ourselves approved rightly dividing the word of truth. May God Bless you Mr. John to continue mentoring even in retirement. God’s word never grows old nor does it retire, you are a blessing.

  26. Thank you John for making an eternal difference in the lives of so many people. God bless you.

    • I thank the Lord for all those whose hearts are filled by the life of their creator to give away what has been given to them so freely. Thank you for loving God and wanting what He wants. For Many to know Him. Like Job who said He knew God but than said He saw God. Thank you John for loving those around you.

  27. Thank you John for saying yes to Christ’ call and letting the Holy Spirit lead you in your spiritual journey. Thank you for your leadership and service with BSF. As a BSF children’s leader the past four years, you are accurate with your assessment of our need to mentor our youth. Thank you for your insights about Jehoida as well. God’s word encourages and inspires and you are living proof of this fact and blessing. May God continue to lead you and bless you in your next phase of life.

  28. Thank you…what a beautiful and powerful reminder and encouragement to share with others God’s Grace through Jesus Christ our Lord and Savior. Mentoring others in both word and deed is truly a blessing to all involved.

  29. Thank you John for years of service. Yes Bsf has also trained me for kingdom living I have held various positions in Bsf and at my church youth leader, prayer leader, woman’s bible study leader, deacon, missions, hope and healing. All because of BSF My best friend has now received Christ I’m so thankful to God

  30. King David almost missed the boat setting the stage for his son Solomon. BSF prepares its participants to be leaders in their church’s and as such, we need to be mindful to train and mentor those that will follow in our footsteps. That happens in part by listening to the Holy Spirit and identifying those around us and preparing them to take over our responsibilities when we no longer can or feel led to continue in our various roles.

  31. Very inspiring indeed. May God show me ways of being an effective mentor

    • Thank you John for the many years you’ve dedicated in doing God’s work. Such an encouraging testimon.
      BSF has a big impact on ones life especially the sharing time.

  32. BSF is fantastic. I thank God every day for leading me to BSF.

  33. Love this blog. It is so important to pass our knowledge on to the younger generations, be it sacred or secular. If this generation fail, the next generation will suffer that gap. So thank you for reminding us to follow God ‘s law.

    • I have just returned to work after six weeks leave. What a timely reminder of how much i need GOD ‘s grace in my life, to have a willing heart and to live for Christ where i work.

  34. What a great encouragement for all of us who have been in BSF for many years. How we need to reach the younger generation as they face so many challenges. Thankful BSF has this desire and I hope each of us will be committed to invite and bring young people to study God’s precious Word!

  35. Excellent blog with great life application

    • Can you resend me the first three messages you sent. I went to check and see if I had read them and they were gone. Somehow they got erased. Thank you so much.

      • Thank you for the reminder that we are in BSF for more than just enriching our understanding of God’s Word, but for also enriching the the lives of others, especially by sharing the gospel with our youth. Thank you, Mr. Amuasi, for your dedication to honor God in all that you do.

        • Thank you Dr. Amuasi for answering God’s call, for your obedience and your service. Your story is inspiring and uplifting. As a BSF group leader I am encouraged to keep serving the Lord by shepherding the ladies that He has entrusted to me, it is a great privilege. May the Lord continue to bless you and your dear wife.

          • Thank you for sharing the value of mentoring. As CS for the Day Woman’s School Program I just took the time this morning to meet with one of my younger CL’s, a mother of 4 elementary school age children. She shared in great detail how much she needs to be mentored. I had no idea! Our getting together for just an hour blessed us both and opened my eyes to the importance of just spending time together to listen and let God take it from there. I know I am going to make an effort to build mentoring time into my week. Your testimony has just solidified my commitment to that. Thank you for sharing.
