Charles H. Spurgeon on Psalms 34:9

O fear the Lord, ye his saints. Pay to him humble childlike reverence, walk in his laws, have respect to his will, tremble to offend him, hasten to serve him. Fear not the wrath of men, neither be tempted to sin through the virulence of their threats; fear God and fear nothing else. For there is no want to them that fear him. Jehovah will not allow his faithful servants to starve. He may not give luxuries, but the promise binds him to supply necessaries, and he will not run back from his word. Many whims and wishes may remain unfulfilled, but real wants the Lord will supply. The fear of the Lord or true piety is not only the duty of those who avow themselves to be saints, that is, persons set apart and consecrated for holy duties, but it is also their path of safety and comfort. Godliness hath the promise of the life which now is. If we were to die like dogs, and there were no hereafter, yet were it well for our own happiness' sake to fear the Lord. Men seek a patron and hope to prosper; he prospers surely who hath the Lord of Hosts to be his friend and defender.
