Israel’s work ethic was shaped by Egyptian slavery. A day off was unimagined. Now God was going to teach them to rest. In today’s sermon, we see God use manna as a tool of instruction. He would provide food for Israel every morning, except the Sabbath. The people would learn to take a Sabbath rest and suffer no loss. God was their sustenance and they were supplied through their obedience. Lessons still true for us today.
