From Wikipedia:
The Reverend David Wilkerson is an American Christian evangelist. He is also the founder of Times Square Church in New York, an interdenominational church.
Wilkerson's sermons are known for being direct and frank. He emphasizes Christian beliefs, such as: God's holiness and righteousness, God's love towards humans and especially Christian views of Jesus. Wilkerson tries to avoid categorizing Christians into distinct groups according to the parish they belong to, and as such he is considered by many to be a truly ecumenical evangelist.
