Charles H. Spurgeon on Psalms 37:7

Rest in the Lord. This fifth is a most divine precept, and requires much grace to carry it out. To hush the spirit, to be silent before the Lord, to wait in holy patience the time for clearing up the difficulties of Providence —that is what every gracious heart should aim at. "Aaron held his peace:" "I opened not my mouth, because thou didst it." A silent tongue in many cases not only shows a wise head, but a holy heart. And wait patiently for him. Time is nothing to him; let it be nothing to thee. God is worth waiting for. "He never is before his time, he never is too late." In a story we wait for the end to clear up the plot; we ought not to prejudge the great drama of life, but stay till the closing scene, and see to what a finis the whole arrives. Fret not thyself because of him who prospereth in his way, because of the man who bringeth wicked devices to pass. There is no good, but much evil, in worrying your heart about the present success of graceless plotters: be not enticed into premature judgments —they dishonour God, they weary yourself. Determine, let the wicked succeed as they may, that you will treat the matter with indifference, and never allow a question to be raised as to the righteousness and goodness of the Lord. What if wicked devices succeed and your own plans are defeated! there is more of the love of God in your defeats than in the successes of the wicked.
