Picture a flock of sheep in a green pasture. What do they normally do there? They eat. When a sheep lies down in a green pasture it can only mean one thing: he’s full. In fact, he’s so full that he has no more desire to eat and lies down.
When David starts Psalm 23 with, “The LORD is my shepherd; I shall not want. He makes me lie down in green pastures. …” he’s saying that he’s so full that even in the presence of what others would call food, he doesn’t feel compelled to eat. His soul is full, from feasting on the presence of the Shepherd. God’s presence is, for David, a satisfaction that no green pasture can ever supply.
This isn’t just a David-thing, though. In the wilderness wandering, God fed the children of Israel with manna, a small cracker-like substance that magically appeared on the ground each morning. And they could only gather enough for one day because it went bad overnight (except on the Sabbath when it would stay good for 48 hours).
The Israelites couldn’t keep any of it in the freezer for later. They couldn’t mix the leftovers into a casserole or keep some in the pantry to make a batch of bread later.
And yet, through this strange bread God met all their nutritional needs while they were in the wilderness. Manna was not supposed to replace food for them for all time; it was just supposed to keep them alive and fed in the wilderness. Manna represented God’s presence in a time of emptiness.
Later, in John 6, we read where Jesus fed the 5,000 with the five loaves and two fish, and He explained that the manna the children of Israel ate in the wilderness was a foreshadowing of His presence with people through the Spirit. He said, “My flesh is the bread that came down from heaven.” And when we feast on Him, we can be full – even in the wilderness, when our bellies feel empty.
When Jesus himself wandered in the wilderness, after fasting for 40 days and nights, Satan appeared to Him and tempted him to … what? To turn the stones into physical bread. And how did Jesus respond? He quoted a verse from the Deuteronomy about manna: “Man shall not live by bread alone, but by every word that comes from the mouth of God.”
So, in our time of wilderness wandering, when we’re in a place that lacks normal bread, we can feast on a better kind of bread – the satisfying bread of God’s promises and presence.
