Here is why you can say to your spouse who has wronged you, “I see your sin, but I can cover it with forgiveness, because Jesus saw my sin and covered it.” It is because the Lord of the universe came into the world in disguise, in the person of Jesus Christ, and he looked into our hearts and saw the worst. And it wasn’t an abstract exercise for Jesus—our sins put him to death. When Jesus was up there, nailed to the cross, he looked down and saw us, some denying him, some betraying him, and all forsaking him. He saw our sin and covered it.
