I respect that your desire attempt to be a slave of God. God is the ONLY one who possesses that TRUTH, YOU and I in our life time will understand little and live out even less, this is why YOU should use greater judgement in the application of your dogmatic rhetoric.
I think your understanding of Andy Stanley is as shallow as your continual criticism of him. I don't think you understand the huge step of faith he took when he and his team started North Point. Rather, your criticism of him and the ministry that NP has is based on the fact that he does not do ministry the EVANG thinks he should.
If you are blessed to reach some people with the message and method that you use....Great.
Grant that others do not have to share your methods and be grateful that they too reach others with the message of redemption.
I have Charles Stanley's books and a number of his podcasts. No not Reformed but a gifted communicator and writer and he openly speaks on sin. I have several podcasts where he does an even better job of that than some Reformed. How to Listen to God is a good one, as well as Success Gods Way.
