A Short Study of Psalm 119:90

“Thy faithfulness is unto all generations: thou hast established the earth, and it abideth.” (Psalm 119:90)


Perhaps Jeremiah said it best, when he said, “It is of the LORD’s mercies that we are not consumed, because his compassions fail not. They are new every morning: great is thy faithfulness.” (Lamentations 3:22-23). At best, our faithfulness is inconsistent and terribly deficient – “for in many things we offend all.” (James 3:2). Oh, but our faithful God knows nothing of inconsistency or unfaithfulness! He is the LORD – He changes not; therefore, we sons of Jacob are not consumed. All that He promises, He brings to pass without fail. David said, “Although my house be not so with God; yet he hath made with me an everlasting covenant, ordered in all things, and sure: for this is all my salvation, and all my desire.” The everlasting covenant of redemption is ordered in all things, but more than that – it is sure. It is sure to all the promised seed – sure to secure us from the wrath to come – sure to supply our every need – sure in every jot and tittle of our salvation – sure because our God is faithful from everlasting to everlasting.

God’s Fixed Earth

In our text, David illustrates the faithfulness of God by calling attention to God’s fixed earth. “Thy faithfulness is unto all generations.” It never fails! It never wavers! It never diminishes! God’s faithfulness to His word, to His promises, to His covenant, and to His bride are perfect, from generation to generation.

How do we know that our God is faithful?

“Thou hast established the earth, and it abideth.”

We know that our God is faithful because the earth is precisely where God placed it at the beginning – firm, and fixed, resting upon immovable pillars built by omnipotent faithfulness.

He “who laid the foundations of the earth that it should not be removed forever” is our faithful covenant God. Just as the heavens declare the glory of God, so the fixed earth beneath our feet declares the faithfulness of God. He will never leave me or forsake me – I know this, not only because He says it, but because the stationary earth that I stand, live, and walk upon bears daily witness to God’s uncompromising fidelity, saying, “God is faithful. He established me from the beginning, and I abide to this day in the very same place – unmoved, firm, fixed, and motionless, without so much as a wobble.”  

A Moving Earth

Children of God, I want you to do something that science falsely so-called renders difficult or next to impossible for most people: I want you to follow an argument. If a fixed, firm, immovable, established earth that abides to this very day declares the faithfulness of our God, what does a moving, orbiting, wobbling, rotating earth declare? It declares that God is unfaithful! If God cannot keep this inanimate object beneath our feet from wobbling, how can He keep that which we have committed unto him against that day? If God cannot preserve His earth upon its foundations, how can He preserve his bride upon the Rock of Ages? If the earth’s foundation is not stable, how is the congregation’s foundation stable? An earth that moves is the product of a false and unfaithful creator who cannot be trusted, but an earth that is fixed and steadfast is the product of the true and living God, who must be trusted. A moving, wobbling, shifting earth reveals a moving, wobbling, and shifting God, but a firm earth that abideth fixed in its place reveals a God who is immutably faithful, a God worthy of our trust and devotion. “Lo, this is our God; we have waited for him, and He will save us: this is the LORD; we have waited for Him, we will be glad and rejoice in His salvation.” (Isaiah 25:9). Let the falsities and fabrications of worldly wise men sink into oblivion. “The LORD reigneth, he is clothed with majesty; the LORD is clothed with strength, wherewith he hath girded himself: the world also is stablished, that it cannot be moved” (Psalm 93:1). Just as certainly as God’s earth cannot be moved, the purpose of God’s grace is firm and fixed forever.

Trust Him

“Thy faithfulness is unto all generations.” His firm fixed earth that bears us up day by day and year after year testifies to that reality. That is David’s precise argument: “Thy faithfulness is unto all generations: thou hast established the earth, and it abideth.”

Trust Him, sinner – trust Him for everything. Trust Him for righteousness. Trust Him for His mercy and grace. Trust Him to keep you to the end. Come to Christ, by Whom all things were made and by Whom sinners are saved, and just as surely as He established the earth that it cannot be moved, He will never cast you out.
