Should conversions happen because people "want to make history" or because "Rick is teaching the class and baptizing and you can get a free photo and book"? Can conversions happen like this? Conversions to Jesus Christ, that is?
Where's the Gospel in this invitation? We can hope it's in the class I suppose...
I can't help but think of 2 Corinthians 4.
2 But we have renounced disgraceful, underhanded ways. We refuse to practice cunning or to tamper with God's word, but by the open statement of the truth we would commend ourselves to everyone's conscience in the sight of God.3 And even if our gospel is veiled, it is veiled only to those who are perishing. 4 In their case the god of this world has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God. 5 For what we proclaim is not ourselves, but Jesus Christ as Lord, with ourselves as your servants for Jesus' sake. 6 For God, who said, “Let light shine out of darkness,” has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ.
True conversion is (and this obviously is not the only way to say it) when the Holy Spirit of God regenerates the unbelieving heart so that, according to Biblical truth, that heart sees, turns towards, and trusts in the glory of Jesus and His cross and turns away from the wretchedness of sin. That certainly could, by God's grace happen with Warren's efforts. But it cannot be manufactured by them. To me, Warren's invite seems to be missing gospel truth, gospel power, and gospel motivation.
