“Faith brings forth praise. He who can trust will soon sing. God’s promise, when fulfilled, is a noble subject for praise, and even before fulfillment it should be the theme of song. It is in or through God that we are able to praise. We praise as well as pray in the Spirit. Or we may read it—in extolling the Lord one of the main points for thanksgiving is his revealed will in the Scriptures, and the fidelity with which he keeps his word of promise.
In God I have put my trust. Altogether and alone should we stay ourselves on God. What was a gracious resolve in the former verse, is here asserted as already done. I will not fear what flesh can do unto me. Faith exercised, fear is banished, and holy triumph ensues, so that the soul asks, “What can flesh do unto me?” What indeed? He can do me no real injury; all his malice shall be overruled for my good. Man is flesh, flesh is grass—Lord, in thy name I defy its utmost wrath. There were two verses of complaint, and here are two of confidence; it is well to weigh out a sufficient quantity of the sweet to counteract the sour.”
- Charles Spurgeon, commenting on Psalm 56:4 in The Treasury of David
