“The LORD is the everlasting God, the Creator of the ends of the Earth. He does not faint or grow weary.” – Isaiah 40:25-31
There is an interesting play at work here in Isaiah that might seem odd. The LORD is the Creator, but then it is emphasized that He does not faint or grow weary. And here we would think about Genesis, about creation, and one of the main points of the story of creation is that on the seventh day God rested.
Well, why did He rest if He doesn’t grow weary?
This is because everything the LORD your God does, He does for your good. On a simple, practical level, He established a day of rest because we need rest. We are not God, we do grow faint and weary, so we need rest. We get worn down, so we need a time of restoration and renewal of our strength, and so God gives this to us.
But more than that. With the impact of sin and death upon the world, our faintness and our weariness increased, and in fact, became fatal. And so the LORD Himself, Christ Jesus, would become Man and He would take up that weakness Himself, and He would suffer and die, and on the seventh day of the week, the Sabbath Saturday after Good Friday, He rested in His tomb. And why? So that He would rise; so that He would raise you up and renew you for all eternity. So that He would bring out the host of His people with not one missing.
It is good to remember that what God does in the Scripture He does simply and solely for your good, for your benefit. This is what it means when we say that the LORD is our God and Creator – that He has done all things, and that all these things are done for you good, given freely as a gift to you. This is Jesus’ great love for you.
