What does it mean that God is the Rock of salvation?
The Bible often pictures God as a rock, and the phrase "Rock of salvation" joins two things at once: what God is like in Himself, and what He does for people who trust Him. It raises the question of how solid our rescue really is, and whether it can shift under us.
A Picture Drawn From Solid Ground
Scripture uses ordinary objects to teach us about God. A rock is chosen because of what it does not do — it does not move.
Derek CooperAs we look at the scriptures we find that God gives many pictures in order to describe Himself. He uses the characteristics of simple objects to help us understand some of His qualities. Many times in the scriptures, particularly in the Old Testament, we read that God is a rock. What an encouragement this is, when all around is shifting and uncertain — we, as Christians, have a solid base for everything. God is a rock, solid, unshifting, permanent.
Salvation That Cannot Slip
If God is the Rock, then the salvation He gives shares the character of its foundation. That has a direct consequence for anyone who fears losing what God has given.
Derek CooperRock of salvation. A completely solid and unshakeable basis for salvation. Whatever aspect of salvation we think of, God is the rock of salvation... As we know, there are some who would teach that we can be saved today and lost tomorrow. The salvation they teach is not based on a rock. With God's salvation we have absolute certainty — He is the rock of salvation.
Him, and No One Else
The psalms that call God a Rock usually add a small word: only. The point is not that God is one support among several, but that everything else is set aside.
F. B. HoleThe Psalmist is very emphatic on this point. His soul waited upon God alone. Literally, it is that his salvation came from Him, and that He, and no one else, was his Rock and his Tower of defence. This being so, we might take it for granted that he was in a place of absolute security and of full assurance.
The Rock That Was Struck
The Old Testament rock is not only a shelter to hide in. In the desert, Israel drank water that came out of a rock that Moses had to strike — and the New Testament identifies that rock.
Truth & TestimonyI would also like to point to the fact that the cleft rock not only gave shelter and safety, but also provided God's people with water during their journey through the wilderness (Ex. 17:6; Num. 20:7-11). The Israelites drank of a "spiritual Rock that followed them: and that Rock was Christ" (1 Cor. 10:4)... Christ is the Rock that was struck with the rod of God's judgment, and His sufferings and His atoning death opened up an inexhaustible fountain of blessing to us.
Perfect Work, Not Just Firm Footing
A rock can be hard and still be indifferent. Moses' song ties the image to God's character, so that stability and goodness are the same thing in Him.
James McBroom"He is the rock; His work is perfect, for all His ways are judgment. A God of truth, and without iniquity; just and right is He." This reveals His stability, His unchanging goodness. The blessed God carries out His own purposes in spite of men's failure and evil and wickedness. There is no flaw in His ways... When you come to God you come to perfection, reliability — that which cannot shift. You have come to that which you can stake your soul upon for time and eternity.
The Danger of Thinking Little of Him
The same song of Moses warns that a people can hold the Rock of their salvation cheap. What causes it is surprising — not hardship, but comfort.
Frank WallaceWhat it simply means is that once the nation got all the blessings that God gave to them, once they entered into the land they had the vineyards, the cornfields, the minerals, the supplies of water. After they had everything that God gave them in His sovereign grace and mercy, they forgot Him. They forgot the One who had given them all these blessings and they lightly esteemed the God of their salvation.
A Rock to Live In
Beyond hiding in God during a crisis, one psalm asks for something more permanent — an address rather than an emergency exit.
Derek CooperA rock of habitation — the King James Version has something a bit different, but this is how it should read. Where we should live — in God and in the conscious knowledge of Him as secure, unmoving, dependable. A rock of habitation — living in Him.
Summary
- Solid — A rock is chosen as a picture of God because it does not shift; when everything around is uncertain, believers have a solid base for everything.
- Struck — The rock in the desert gave water only after it was struck, and that Rock was Christ; His atoning death opened the fountain of blessing.
- Sure — Salvation built on a Rock is a salvation of absolute certainty, not one held today and lost tomorrow.
- Sole — The psalmist's confidence came from waiting on God alone: He, and no one else, was his Rock and tower of defence.
- Sustained — The danger is comfort: Israel received every blessing, forgot the Giver, and lightly esteemed the Rock of their salvation. The alternative is to live in Him — a rock of habitation.
