Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. - 2 Corinthians 5:17
Most carpenters will say that it is always better and usually more economical to construct a new house than to patch up an old one. This is even more true in the spiritual realm. There is nothing in our old nature worth salvaging. Our thoughts are full of deceit. Our mouths are filled with cursing and bitterness. The way of peace we have not known. The Bible says, “there is none that doeth good, no, not one.” (Psalm 14:3).
The old nature with its deceitfulness, its depravity, and its wickedness must give way to a new nature. And this is exactly what God wants for us. God says, “A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh.” (Ezekiel 36:26).
It is much more difficult to change our dispositions than it is our apparel. As a matter of fact, it is utterly impossible for us to change our disposition in our own strength. Like David, we can ask for help! “Create in me a clean heart, O God; and renew a right spirit within me.” (Psalms 51:10).
Have to put off the old man in its entirety, and put on the complete new man in His image!
