You don't know but you're perfectly willing to cast doubt on his ministry. A ministry that uses a biblical definition of the gospel as I demonstrated to you here. You didn't respond to that post which demonstrates Warren defines the gospel as you do. But to you he's a false prophet. If true and you define the gospel the same way, what does that make you?
I cast doubt on him because I have read his own words and many critiques of him, and drawn my own conclusions. What I don't understand is why so many are so anxious to follow him, defend him, and be his disciples. Why do people seem to have so much emotion and belief invested in Warren or any other man? When people tried to lift up the Apostle Paul or other men in the church, Paul told them to stop. So did John the Baptist.
