“Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.”
King James Version (KJV)
5:17 Therefore if any one be in Christ - A true believer in him. There is a new creation - Only the power that makes a world can make a Christian. And when he is so created, the old things are passed away - Of their own accord, even as snow in spring. Behold - The present, visible, undeniable change! All things are become new - He has new life, new senses, new faculties, new affections, new appetites, new ideas and conceptions. His whole tenor of action and conversation is new, and he lives, as it were, in a new world. God, men, the whole creation, heaven, earth, and all therein, appear in a new light, and stand related to him in a new manner, since he was created anew in Christ Jesus.
2Co 5:17 If any man [be] in Christ, [he is] a new creature. Because, crucified with Christ, buried into his death, we have died with Christ, and risen to walk in a new life (Ro 6:6,4,14). Born anew, we are new creatures who must live a new life. Old things are passed away. The old life ended when we died and were buried. All things have become new. The affections, the motives, the thoughts, the hopes, the whole life.
