The first time the idea of “rest” is explored in the Bible is actually within the first two chapters. It’s a story with which you’re likely familiar. On the seventh day of Creation, after ordering the universe and preparing a world where humans could flourish, God rests (Gen. 2:2).
For us today, these words conjure up an image of God somehow wiping the sweat from His brow, plopping down in a chair, and putting His feet up. As if somehow God could be exhausted after a long (six) days of work.
