Charles H. Spurgeon on Psalms 4:8

Due observation of Providence will both beget and secure inward tranquillity in your minds amidst the vicissitudes and revolutions of things in this unstable vain world. "I will both lay me down in peace, and sleep; for the Lord only maketh me dwell in safety." He resolves that sinful fears of events shall not rob him of his inward quiet, nor torture his thoughts with anxious presages; he will commit all his concerns into that faithful fatherly hand that had hitherto wrought all things for him; and he means not to lose the comfort of one night's rest, nor bring the evil of to-morrow upon the day; but knowing in whose hand he was, wisely enjoys the sweet felicity of a resigned will. Now this tranquillity of our minds is as much begotten and preserved by a due consideration of providence as by anything whatsoever. John Flavel, 1627 - 1691.
