If your church has regular altar calls where the preacher or evangelist says, "Every head bowed, every eye closed. Now, if you are sure, beyond a shadow of a doubt, that you are saved and going to heaven, please raise your hands. Thank you, thank you, hands going up all over the auditorium. But some of you couldn't raise your hand. Now, while the organ plays softly, and the choir sings a few dozen choruses of 'Just As I Am,' I want those of you who could not raise your hands to walk the aisle and come forward and kneel at the altar" etc. etc. If your church has some variation of this appeal - then you may be IFB.
I do not wish to condemn those who, in all sincerity, make these kinds of appeals. But I don't see anything like this in the New Testament. I don't see the record of Christ and the apostles conducting this sort of "altar call" on the beaches of the Sea of Galilee, or Paul doing this on Mars Hill or anywhere else. I would prefer that we avoid emotional or psychological manipulation in whatever form of "invitation" is used, and rely on the Holy Spirit to do His convicting work.
