The sinful nature is the stubborn, self-centered attitude that says, “My way or the highway.” The sinful nature is all about self: pleasing self, promoting self, preserving self. I have a sin nature; so do you. Under the right circumstances you will do the wrong thing. You’ll try not to, but you will. You have a sin nature. You were born with it. The heart of the human problem is the problem of the human heart.
Christmas commemorates the day and the way God saved us from ourselves. The angel speaking to Mary in Matthew 1:21 says, “…you are to give him the name Jesus, because he will save his people from their sins.” Each of us entered the world with a sin nature. Each of us entered the world with a sin nature; God entered the world to take it away.
