I have heard this system of evangelism. Just get'em to say the sinners prayer. Is it effective, is it valid, is it eternal. I attended a seminar by Church Growth Institute several years ago. The one thing I remember being said was that we often have heard a preacher say "You may walk out this church tonight, get hit by a truck and never have the opportunity to receive the Gospel again" The speaker went on to ask if we have ever seen that happened. The point he was leading to, is that true evangelism may take weeks or months to accomplish. The plan was to establish a relationship with the individual you desire to witness to. Thoughts?
