Re Decisional Regeneration

While the words "make a decision for Christ" are not used in Scripture, the fact that we are commanded to repent seems to imply an exercise of the will. 

Instead of "inviting Jesus into your heart", which is a foreign concept in scripture, we should urge repentance and throwing ourselves on the mercy of Christ and His finished work on the cross.

"We must preach the gospel that they are sinners, but that Christ has come to save sinners just like them. We must not deviate from the Scriptures in order to win more bodies while we give false assurance to souls."
