God commands us to tell the truth. He was living in sin.
And I’m telling you the truth: you are not God. You are not Saint Peter. Your place as an ambassador for Christ is not to wag your finger haruumphing self-righteously at other people’s sins, but rather to look to the log in your own eye. Unless, of course, your life is spotless. From what I heard, there has only ever been one perfect human.
Your personal interpretations or your denomination’s dogma may be the eternal Truth, or they may be a little off kilter. You won’t know until you get there and meet the real Judge.
