Charles Spurgeon Commentary Colossians 3:9-10

"lie not one to another; seeing that ye have put off the old man with his doings, and have put on the new man, that is being renewed unto knowledge after the image of him that created him:" — Colossians 3:9-10 (ASV)

Seeing that you have put off the old man with his deeds; and have put on the new man, which is renewed in knowledge after the image of him that created him:

There is nothing false or untrue in God. God is true, and in him is no falsehood at all; and if you and I have really been renewed, as we profess to have been, we shall hate the very semblance of a lie, and our word will be as good as our bond.
