We overcome failure when we realize that God is not even remotely embarrassed by our weaknesses. He defends us to all our detractors. He is not ashamed to call us brethren. We are in Christ and cannot be condemned [Romans 8]. He is the One who loves us the best and knows us the best. God does not get disillusioned with us because He has no illusions in the first place!
