In 1988, Bishop Oriel M. Ballano (BOMB or 'The BOMB' as his church endearingly calls him) felt God speak to him about having a ministry that would grow to have so many people primarily from the campuses. On the same year, BOMB with his wife Geraldine founded the Doulos for Christ World Harvest Ministry (DFC), starting with a small group of people from the Far Easter University. Today the church has more than eleven thousand members.

DFC grew as BOMB followed Jesus' example of building the church on a foundation of 12 disciples. He adopted the G12 vision in 2003 to train twelve people that are able to reproduce the character of Christ in each of them and they in turn are able to do the same with another twelve and so on, then the church experienced unprecedented growth. Today, the influence of his church that had such humble beginnings in Manila extends all over the nation.

BOMB was ordained Bishop by the Philippine Council of Evangelical Churches (PCEC) February 2010.

BOMB is the G12 coordinator for the Philippines, serving under Ps. Cesar Castellanos, founder of the G12 Vision. He is an inspirational pastor that has many recorded teachings about church growth, discipleship, and the G12 vision in conquering cities for Christ. He is also now becoming a well-sought-after international speaker in Asia and in the United States.

Pastor Geraldine C. Ballano has faithfully served alongside her husband since the birth of DFC. Leading one of the largest networks of women in the nation, she is responsible for over 8,000 women inside the cell groups of DFC. BOMB and her have three daughters, and a son. They all work together as a family in ministry.
