After years of ministry as station pastor of the Gospel Revivals Ministry, Rev. J.F.K. Mensah and his wife, Georgina Mensah sensed they were being called to a ministry of training Christians in down-to-earth practical topics and grooming them in evangelistic tools to fulfil the Great Commission.
Starting with a core group of seven young men and women, the Mobile Evangelistic Unit lasted for seven years within which the meetings grew to a membership of 107 in 1991. Topics like Repentance and New Birth, Water Baptism, Holy Spirit Baptism, Deliverance from Curses and Demons, Marriage, Soulwinning, Rural Church Planting, etc. were taught as transferable concepts.
The principle of fruitfulness from Jn. 15 was that each year, before a member qualified to attend a meeting, he had to win, groom or teach one other person whom he would bring along. A vow was taken to finish the work of the Great Commission within forty years using this strategy.
