Passing the torch

“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.

  1. As I get older I value life so much more and have a deep compassion for young people. THANK you for sharing that compassion and the encouragement: One life at a time. For the need seems so over whelming until I realized the ONE life that saved us all. And the one life I have and you have. And the many you in the world….one life at a time telling of the ONE that died for us all. I needed those encouraging words. THANKS!!!

  2. Thank you for your contribution to BSF and for reminding us that we can serve God through our work.

  3. Dr. Amuasi is a source of encouragement to all of us.
    It is also a challenge on our role in mentorship.

  4. Thank you Dr, John. May you continue to impact the lives of others
