7 for we walk by faith, not by sight.
16 Therefore we know no one according to the flesh from now on. Even though we have known Christ according to the flesh, yet now we know him so no more. 17 Therefore if anyone is in Christ, he is a new creation. The old things have passed away. Behold,5:17 "Behold", from "ἰδοὺ", means look at, take notice, observe, see, or gaze at. It is often used as an interjection. all things have become new.
21 For him who knew no sin he made to be sin on our behalf, so that in him we might become the righteousness of God.
