The last phrase of Psalm 18:31 addresses just the point where many people make the biggest mistake in their lives. The verse says: “For who is God, but the LORD? And who is a rock, except our God?” (Psalm 18:31) The implied answer is, of course, no one! There is no God but Yahweh; there is no rock except our God. Which is where many of us miss it.
The term “a rock” implies security, safety, peace, refuge. People look for these things in so many places: in their job; in their money; in their family; in their career; in some special person. But the Bible makes it clear that there is only ONE place where it may be found: in the God of the Bible. He is the “rock” of security so many are looking for. In fact the insecurities that plague so many people come from the fact that they are seeking peace and security where it cannot be found — in people and things which are temporary. That’s why David’s statement in Psalm 16:5 is so poignant: “Yahweh is the portion of my inheritance and my cup; You support my lot.” David’s “inheritance”, his “portion” was the LORD, Someone who would always be there and who would always be a “rock” for him. That was the basis of the peace that he subsequently manifested.
David repeatedly evidenced a marvelous testimony of peace, even in the midst of what would have been stressful times, because God was his security, his “rock.” The question each of us should ask ourselves is, “Do others see this in me? Do I have that kind of peace?” If we have built our lives around something besides God, we will show it when the “storms” of life come and they are taken away; there is no “faking it.” Just like Jesus said in Matthew 7, when the floods come and the winds blow and burst against us, it is only the house that is “built upon the rock” which will stand. And as David asserts here, the God of the Bible, whom we know through Jesus Christ, is that one Rock.
Who or what are you building your life around? God gives us a many relationships and things to enjoy here on earth, but as we see in Psalm 18:31, there is only ONE “Rock”!
