"Behold I will stand before you there on the Rock at Horeb; and you shall strike the Rock, and water will come out of it, that the people may drink." And Moses did so, in the sight of all the elders.
I Corinthians 10:4 tells us that it was a spiritual Rock that followed them in the Desert, and that Rock was Christ.
Moses was told to strike the Rock, as Jesus was struck down once for all in Crucifixion (Hebrews 10:10-14 & I Peter 3:18), and so much water poured out of it that all those people (millions!) had enough to drink, and water all their animals, as much and more than they all needed.
But when they came back to the Desert of Sin and needed water again, God told Moses to speak to the Rock, because He had already struck it before. But in his anger at the people, he struck it again, twice, and the water still flowed. But Moses had damaged the picture of what Christ would do, and was forbidden to enter the Promised Land with the people (Numbers 20:1-13 & Deuteronomy 34:1-4.) God is serious about our understanding of Who He is and what He does for us.
Jesus is our Source of Life, the life-giving water that we all need. He is sufficient to meet all my needs, even when He uses improbable and impossible sources. Even when I cannot see at all how my needs can be met, He will always come through for me.
Even so, come, Lord Jesus!
