For William, Ephesians 4:11–13 is a crucial passage: “And He gave some as apostles, and some as prophets, and some as evangelists, and some as pastors and teachers, for the equipping of the saints for the work of service, to the building up of the body of Christ; until we all attain to the unity of the faith, and of the knowledge of the Son of God, to a mature man, to the measure of the stature which belongs to the fullness of Christ”.
In light of this scripture, William is focused on equipping the saints for the work of ministry. His heart is to see the body of Christ become a mature man unto the measure of the stature that belongs to the fullness of Christ. As Jesus himself walked the earth as a mature son, William’s passion is to see the body of Christ walk in the same manner, thus fulfilling the declaration Jesus made in John 14:12, that we would do the works He did and even greater.
In William’s case, these motivations take the shape of itinerant ministry and discipleship. In regards to itinerant (traveling) ministry, William says, “I believe that by traveling across the world equipping churches through conferences, training workshops, power evangelism, and missions that we are helping them step into their fullness.” He describes his heart for discipleship as a belief that by helping churches develop their discipleship programs through focus on Jesus’ model of discipleship, they will help to mature the body of Christ.
