But Moses’ hands grew weary, so they took a stone and put it under him, and he sat on it, while Aaron and Hur held up his hands, one on one side, and the other on the other side. So his hands were steady until the going (Exodus 17:12)
Israel is in battle with Amalek, and victory depends on something strange: as long as Moses holds his staff up, Israel prevails. But Moses' arms grow tired and whenever they drop, Israel begins to lose. So Aaron and Hur put a stone under him to sit on, and they stand on either side and hold his arms up, one on each side, until the sun goes down.
Notice who actually wins that battle. Not Moses, his arms failed. Not Aaron and Hur, they only held up a tired man. It was God who gave Israel the victory, and He chose to give it through Moses, and through the two who steadied him when his own strength was gone. The deliverance comes through human weakness.
On Sunday Brandon said "we are not as strong as we think". That's not bad news (although it often seems like it) because it's where we see our need for God. He is not waiting for you to stop needing help; he is the one who gives you what you need, and often through those who walk with you. There's no shame in being the tired man on the hill, the problem comes when our pride says I can do it on my own and I don't need help.
How have those around you helped steady your arms? How can you help those around you by lifting up their arms?
