Give the BGEA credit where it's due. They have kept statistics on the results of their "crusades" over the decades, and inform us that 4% of those who "make a decision for Christ" actually become active Christians. This would indicate that the "crusade evangelism" approach -- inducing conversions through various techniques of emotional manipulation -- has a 96% defect rate. People have some kind of experience induced by the event, which fails to last too far beyond the event that created the experience.
I have a personal conviction against responding to altar calls.
"I have a personal conviction against responding to altar calls."
Especially since the gospel itself is all the invitation anyone ever needs. The danger of altar calls, in my opinon, is that the evangelist tends to take over the Holy Spirit's job of giving people the assurance of salvation. It would seem that many people leave these crusades with a false sense of security.
