John gave his life to the Lord at the age of 25 and has served Him in different capacities ever since.

Together with his wife Sandra, he has been the Program Director for "Alpha", an evangelical and discipleship program which witnessed countless numbers of people come to know and grow in the Lord for almost 20 years.
