Are you saying Mr. Driscoll is not a servant of Jesus Christ? If he is, and so are you, then your reference doesn't really make sense.
That said, I agree with your post wishing his future congregants well. I'm concerned at the way his decision to proceed is portrayed: as his decision. One recent emphasis I've received from the Lord is not to go off half-cocked under my own steam, to mix metaphors, but rather to proceed not on my projects but instead on His. He says he is "hoping, trusting, praying, planning and also a little...worrying about planting a church here." How about "obeying?"
Romans 14:4 (KJV) Who art thou that judgest another man’s servant? to his own master he standeth or falleth . Yea, he shall be holden up : for God is able to make him stand .
