Even if you’ve heard it before, sometimes it’s good to cover the same ground again. When Jesus died on the cross He covered our sins.
Cover is an interesting concept. To cover the bill is not to put your salad plate on top of it, but to pay the full amount. To cover a mistake, at least in a good way and not a cover-up, is to do what it takes to fix the problem.
Cover is a way to speak about atonement as well. David sang so.
Blessed is the one whose transgression is forgiven,
whose sin is covered. (Psalm 32:1)
The Lord covers our guilt, restores us to fellowship with Him, and overcomes many of the consequences of our sin. When Adam and Eve knew that they were naked, the LORD covered them better than they covered themselves. When we knew that we were naked in our filth, the Lord covered us with the righteousness of His own Son.
Even more than that,
For while we are still in this tent, we groan, being burdened—not that we would be unclothed, but that we would be further clothed, so that what is mortal may be swallowed up by life. He who has prepared us for this very thing is God, who has given us the Spirit as a guarantee. (2 Corinthians 5:4–5)
He will cover our mortality with eternal life. The clothing is the life of Jesus Christ. It is mercy to us even as the bread and the cup reminds us of the judgment. So the Lord’s Supper is a sober celebration that He has us covered.
