Everyone is looking for something that will not move — something solid enough to build a life on, to stand on when everything else gives way. The Bible has a word for that: a Rock. And it says, with a boldness that is easy to miss, that the Rock is a Person.
Water from the rock
Israel was dying of thirst in the desert, ready to stone Moses, when God gave a strange command: strike the rock.
“Behold, I will stand before thee there upon the rock in Horeb; and thou shalt smite the rock, and there shall come water out of it, that the people may drink.” — Exodus 17:6
Moses struck it, and a river ran out of solid stone for a whole nation. It was a miracle in its own day — but centuries later Paul reaches back to that rock and tells us what it really was:
“They drank of that spiritual Rock that followed them: and that Rock was Christ.” — 1 Corinthians 10:4
That one line is the key to everything. The rock in the wilderness was a picture, and the picture was of Jesus.
Smitten once
Look closely at what had to happen before the water came: the rock had to be struck. That is the gospel in a single image. Christ was “smitten of God, and afflicted” (Isaiah 53:4) — struck once, in our place, so that life could pour out to us.
And here is the detail that makes the picture unmistakable. Years later, at Meribah, the people thirsted again, and this time God told Moses only to speak to the rock. Instead, in anger, he struck it — twice (Numbers 20:8–11). The water still came, but it cost Moses the Promised Land. Why so severe a price for one act of temper? Because he had broken the picture. The Rock is smitten once. After Christ “was once offered to bear the sins of many” (Hebrews 9:28), you do not strike Him again — you simply speak to Him. Moses, by striking the second time, marred the very type God was painting of His Son.
The water is the Spirit
What was the water that gushed from the smitten rock? Jesus Himself told us what it pictures, standing in the temple and crying out:
“If any man thirst, let him come unto me, and drink… out of his belly shall flow rivers of living water. (But this spake he of the Spirit…)” — John 7:37–39
The Rock was struck so that the Spirit could flow. From the smitten Christ comes the living water — the Holy Ghost, poured out on all who come and drink. Which is exactly the promise Peter preached when the church was born: be baptized in the name of Jesus Christ, “and ye shall receive the gift of the Holy Ghost” (Acts 2:38). The thirsty don’t have to strike the Rock; they only have to come.
The Rock is Jehovah
Now follow the thread back through the Old Testament, because it leads somewhere glorious. Over and over, God is called the Rock — and not as a passing poetic image, but as one of His great names:
- “He is the Rock, his work is perfect” (Deuteronomy 32:4), and “of the Rock that begat thee thou art unmindful” (32:18).
- “There is none holy as the LORD… neither is there any rock like our God” (1 Samuel 2:2).
- “The LORD is my rock, and my fortress… my God, my strength, in whom I will trust” (Psalm 18:2).
- “Trust ye in the LORD for ever: for in the LORD JEHOVAH is everlasting strength” (Isaiah 26:4) — the Rock of Ages.
In every one of those verses, the Rock is Jehovah. And Paul says that Rock “was Christ.” Put the two statements side by side and the conclusion cannot be avoided: Jesus is that Rock — the same unchanging Jehovah the Scriptures always meant, now our Saviour in flesh. The Rock of the Old Testament and the Christ of the New are not two; they are one.
The stone the builders rejected
From rock to cornerstone. The same Christ is the stone a building rests on — and the stone men trip over.
“The stone which the builders refused is become the head stone of the corner.” — Psalm 118:22
Jesus quoted that of Himself (Matthew 21:42), and Peter preached it to the very rulers who crucified Him (Acts 4:11). Isaiah had foreseen Him as the sure foundation God lays in Zion, “a precious corner stone” (Isaiah 28:16). And Peter draws the two edges together: to those who believe, He is precious; to those who refuse, He is “a stone of stumbling, and a rock of offence” (1 Peter 2:6–8). The same stone is either the foundation you build on or the one you fall over. There is no third option.
“Upon this rock”
Which brings us to a famous and debated verse. When Peter confessed, “Thou art the Christ, the Son of the living God,” Jesus answered, “upon this rock I will build my church” (Matthew 16:16–18). Some take the rock to be Peter himself. The Apostolic understanding — and, we would say, the one the rest of Scripture requires — is that the Rock is Christ, confessed and believed: “other foundation can no man lay than that is laid, which is Jesus Christ” (1 Corinthians 3:11). Peter’s own name means a stone (petros); the bedrock (petra) the church is built on is the Christ he had just confessed. Peter is built on the Rock with all the rest of us — not set up as the Rock over us.
Build on the Rock
So the invitation of the whole subject is simple. Jesus ended the Sermon on the Mount with it: the wise man built his house “upon a rock,” and when the rain and floods and winds came, “it fell not: for it was founded upon a rock” (Matthew 7:24–25). The house on sand fell. The difference was not the storm — both got the same storm — but the foundation.
And as Moses once hid in the cleft of the rock while the glory of God passed by (Exodus 33:22), so there is a cleft in this Rock for you — opened by the smiting, wide enough to hide in. The Rock has already been struck, once, for you. You do not have to strike Him. You only have to come, and drink, and build your life on the One who does not move.
“Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.” — Acts 2:38
