Charles H. Spurgeon on Psalms 16:1

"For in thee do I put my trust." Here the prophet setteth down the cause why he prayeth to God; whereby he declareth, that none can truly call upon God unless they believe. Romans 10:14. "How shall they call on him in whom they have not believed?" In regard whereof as he prayeth to God to be his Saviour, so he is fully assured that God will be his Saviour. If, then, without faith we cannot truly call upon God, the men of this world rather prate like parrots than pray like Christians, at what time they utter these words; for that they trust not in God they declare both by neglecting the lawful means, and also in using unlawful means. Some we see trust in friends; some shoulder out, as they think, the cross with their goods; some fence themselves with authority; others bathe and baste themselves in pleasure to put the evil day far from them; others make flesh their arm; and others make the wedge of gold their confidence; and these men when they seek for help at the Lord, mean in their hearts to find it in their friends, good authority and pleasure, howsoever for fear, they dare not say this outwardly. Again, here we are to observe under what shelter we may harbour ourselves in the showers of adversity, even under the protection of the Almighty. And why? "Whoso dwelleth in the secret of the Most High, shall abide in the shadow of the Almighty." And here in effect is showed, that whosoever putteth his trust in God shall be preserved; otherwise the prophet's reason here had not been good. Besides, we see he pleadeth not by merit, but sueth by faith, teaching us that if we come with like faith, we may obtain the like deliverance. —Richard Greenham.
