Charles H. Spurgeon on Psalms 73:26

My flesh and my heart faileth. They had failed him already, and he had almost fallen; they would fail him in the hour of death, and, if he relied upon them, they would fail him at once. But God is the strength of my heart, and my portion for ever. His God would not fail him, either as protection or a joy. His heart would be kept up by divine love, and filled eternally with divine glory. After having been driven far out to sea, Asaph casts anchor in the old port. We shall do well to follow his example. There is nothing desirable save God; let us, then, desire only him. All other things must pass away; let our hearts abide in him, who alone abideth for ever.
