"Only after we are thoroughly convinced that God's Word is powerful enough to save (without added methods or techniques) will we be able to do away with the man-made altar call system. But when we do, we are able to see God work in people's lives without our manipulative interference. As a result, all of the glory goes to the Lord--and we can concentrate on being faithful in urgently inviting people to Christ rather than being numerically successful."- Carey Hardy
