"If the Scripture teaches that truly knowing God - knowing Christ - guards and guides and governs our sexuality in purity and love, then we may be sure that a pastor, or anyone else, whose sexuality is not governed and guarded and guided in purity and love does not know God - at least not as he ought."- John Piper
