I have stayed up many nights, for months, into the wee hours crying and praying, and physically trembling before God before I took that step with complete assurance, and before I rebuked my own pastor for his cavalier, deceptive, politicking attitude and behavior.
Did you accuse your pastor of Apostasy? Or were you concerned that perhaps he had left his first love? The Church at Ephesus was not apostate. Warren has a different vision of the mission of his church. You disagree with it. You are free to find a new fellowship. Warren's sermons may be pablum for the spiritually filled, but they are often filled with milk for the spiritually weak and hope for the spiritually dead. Say what you will, but I suspect that they are a lot closer to the full gospel than you will get at a lot of other churches.
