“It amazes me that anyone would dare point to Jesus Christ in moral judgement. You had better have clean hands and a pure heart before you point a finger at the Son of God… Jesus never sinned once, in thought, word, or in deed. He never lied, stole, hated, lusted, coveted, murdered, or dishonoured his parents. Let's now turn the mirror back on you. When was the last time you burned with unlawfully sexual fantasies? You don't need to reply to that. God knows the answer… So take a little advice from a fellow sinner - stop pointing your sin-stained finger at perfection, and instead look at your own self-righteous and duplicitous heart, before it's too late.”
