Christ tells us to tell them about Him ...If we start leaving out the main ingredient...
And I was responding to your above comment. From Warren's book we see he does indeed teach others the importance about the Great Commission, and how it's the main ingredient.
Yes, but he talks more about how we are to serve other's and that is how I believe he thinks the great commission is all about.
He doesn't speak about how we are sinners and need to come to Christ. He leaves out key ingrediants out of Christianity. It is a seeker friendly style. There are many other things about Warren I don't like, but I've seen enough to know I think he is full of crap.
