St Paul said Christians will always be out of step with the world until every knee is bent...Bonhoeffer said Christians will always be a small, persecuted minority, if they are true to their discipleship.
Warren does good works but from what I've seen, anyone from a Christian to a "good atheist" could do what he does. He seems genuinely confused by these worldly things.
I am astonished that you are so quickly deserting the one who called you by the grace of Christ and are turning to a different gospel— which is really no gospel at all. Evidently some people are throwing you into confusion and are trying to pervert the gospel of Christ. But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let him be eternally condemned!
Galatians 1:6-8
Sounds to me like Paul was talking about Warren and the other prosperity preachers.
