In the bible there is little support for the level of churches and materials aimed at doing this. I do not think there is anything wrong with this ministry it's just when people neglect to evangelize to men but rather to children is where there is. Problem. Back at BJU I can think of a dozen students that would much rather be doing children's evangelism and setting up camps and sports parks and so forth over witnessing to men. Looking at the book of Acts I do not find support for this nor do I from the life of Jesus and Paul. Grew up Arminian but moved towards Calvinism after school and the more Reformed colleges and seminaries are doing things closer to the biblical model.
