Time

“Maturing in Christ takes time. There is no way that children can be raised in a hurry. To try to get it over quickly can only lead to frustration. The hectic way that churches have tried to force this in to a few weeks of confirmation classed, it they have done it at all, is entirely inadequate. Disciples must have devoted Christian friends to follow, and this can only be facilitated by being together over a period of time.”

― Robert E. Coleman, The Master Plan of Evangelism
