C.S. Lewis has this really helpful illustration. He says that in the incarnation, Jesus was like a diver. He is God in heaven looking down into this dark, slimy, murky water. That’s our sinful, polluted world. God dives in, He gets himself wet. And then God came up again, dripping, but holding the precious thing he went down to recover. That precious thing was Zacchaeus, and you and me. All those sinners who have trusted in Christ. That’s how we get out of the slime of tax collecting, or cheating, or lusting, or hating, or whatever other self-destructive sin we are buried in. God in Christ descended down into the slime and rescued us. Resolutions and vows to be better won’t help by themselves. We don’t have the power to keep them. We are stuck on the sea bottom. We have no power of our own to get up or out. All we can do is cry out for God’s grace to lift us up, to rescue us.
