Charles H. Spurgeon on Psalms 119:90

Thy faithfulness is unto all generations. As he gathered, the certainty of God's word from the endurance of heaven, so now he confirms it by considering the foundation of the earth. Since the foundation of the earth, made by the word of God, abides sure, shall we not think that the foundation of our salvation laid in Jesus Christ, is much more sure? Though the creatures cannot teach us the way of our salvation (for that we must learn by the word), yet do they confirm that which the word saith, "Thus saith the LORD, which giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; the LORD of hosts is his name: If those ordinances depart from before me, saith the LORD, then the seed of Israel also shall cease from being a nation before me for ever:" Jeremiah 31:85, Jeremiah 31:36. As there Jeremy gathers the stability of the church from the stability of the creatures; so here David confirms the certainty of our salvation by the most certain and unchangeable course of creation; and both of them are amplified by Christ Jesus: "Heaven and earth may pass away, but one jot of God's word shall not fall to the ground." Let us therefore be strengthened in faith and give glory to God. William Cowper.
