When God miraculously provided just enough manna for the Israelites, Scripture says that He provided just enough. The language describing God’s provision is extremely precise. Those who gathered a lot “did not have too much” and those who gathered a little “did not have too little.” God provided just enough. Then He gave them a curious command: not to keep any of it overnight.
Why does God provide just enough? Why would God forbid leftovers? What’s wrong with taking a little initiative and gathering enough manna for two days or two weeks? Here’s my take: the manna was a daily reminder of their daily dependence upon God.
Not much has changed. We still need a daily reminder of our dependence upon God. So while we may want a one-year supply of mercy, His mercies are new every morning. If God provided too much too soon, we’d lose our raw dependence upon God, our raw hunger for God. So God usually provides just enough, just in time.
I have scribbled the initials JEJIT in the margins of my Bible at various places where God provides just enough, just in time. He does it with the widow who is down to her last jar of olive oil. He does it when the Israelites are trapped between the Egyptian army and Red Sea. He does it when the boat is about to capsize on the Sea of Galilee during the perfect storm. And He does it again with the two fish and twenty thousand hungry people.
