In 1984, God called John into full-time ministry with Youth for Christ Singapore. Subsequently he went to study Diploma in Theology in Sydney (1990), BTh in Singapore Bible College (1995) and Master in Ministry in Melbourne (2006). He has served in the Presbyterian churches locally.
He is thankful to God for calling him from retirement to serve part-time in ORPC. Our Lord has impressed upon his heart to serve in the Small Group ministry. John believes it is a place where church members meet regularly, through Bible Study to learn in more detail about the Word, connecting with one another, encouraging and spurring one another toward godliness. Furthermore, Small Group ministry provides opportunities for church members to work as a team to reach out to non-Christian relatives and friends.
John is a part-time pastoral staff serving in Congregational Care and Discipleship Group ministries.
