Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new.
— 2 Corinthians 5:17
Can the leopard change its spots? Can the Ethiopian change his skin? Of course not. No more than human beings can change their nature; but that is precisely what Christ does. He doesn’t merely change our outward behavior; He changes our nature. He comes within us and plants therein a new man and a new nature—a new creation created by God—a new you.
In Christ, we now desire things we didn’t desire before. Christ did that to me. God placed a screwdriver in my “wanter” and turned it upside down, and to my utter amazement, I now wanted things I had never wanted before.
Charles Spurgeon said that if you were to take a hog out of the mud and the mire, out of the trough and the herd, and by some magic wand transform him into a prince sitting upon a throne, he would not be changed as much as when God Almighty by His grace transforms a depraved sinner into a prince of the Royal Realm. He is now a child of the King of kings, living in a dominion that has neither end nor limit of extent.
