Yet, his teams are on the cutting edge in reaching people of different ethnicities and including the marginalised, the poor and those with special needs.
Using both friendship and preaching, outreach teams go to places of public interest, parks and shopping malls. Complementary gifts are developed so that one person may illustrate a message with painted art work and others play music. Imaginative means characterise OAC evangelism with puppetry and creative object lessons drawing in passers-by. When they stop and listen to the brief Gospel message, other team members follow-up with conversation and literature distribution.

"Now I want to repeat the process for others."
His activities include teaching sketchboard painting to OM Lifehope students and those on a more advanced level and mentoring younger friends in coffee shops. He also enjoys conducting seminars and helping churches with practical outreach. John feels it's important to help develop gifts among people who do not preach and become valued team members. It seems that the West Midlands teams have room for everyone who is dedicated to serve on the cutting edge of effective evangelism.
