Psalms 30:7

7.O Jehovah! of thy good pleasure. This verse describes the difference which exists between the confidence which is founded upon the word of God and the carnal security which springs from presumption. True believers, when they rely upon God, are not on that account neglectful of prayer. On the contrary, looking carefully at the multitude of dangers by which they are beset, and the manifold instances of human frailty which pass before their eyes, they take warning from them, and pour out their hearts before God. The prophet now failed in duty as to this matter; because, by anchoring himself on his present wealth and tranquillity, or spreading his sails to the prosperous winds, he depended not on the free favor of God in such a manner as to be ready at any time to resign into his hands the blessings which he had bestowed upon him. The contrast should be observed between that confidence of stability which arises from the absence of trouble, and that which rests upon the gracious favor of God. When David says that strength was established to his mountain, some interpreters expound it of mount Zion. Others understand by it a stronghold or fortified tower, because in old time fortresses were usually built upon mountains and lofty places. I understand the word metaphorically to signify a solid support, and therefore readily admit that the prophet alludes to mount Zion. David thus blames his own folly, because he considered not, as he ought to have done, that there was no stability in the nest which he had formed for himself, but in God’s good will alone.

Thou hast hidden thy face. Here he confesses, that, after he was deprived of God’s gifts, this served to purge his mind as it were by medicine from the disease of perverse confidence. A marvellous and incredible method surely, that God, by hiding his face, and as it were bringing on darkness, should open the eyes of his servant, who saw nothing in the broad light of prosperity. But thus it is necessary that we be violently shaken, in order to drive away the delusions which both stifle our faith and hinder our prayers, and which absolutely stupify us with a soothing infatuation. And if David had need of such a remedy, let us not presume that we are endued with so good a state of heart as to render it unprofitable for us to be in want, in order to remove from us this carnal confidence, which is as it were diseased repletion which would otherwise suffocate us. We have, therefore, no reason to wonder, though God often hides his face from us, when the sight of it, even when it shines serenely upon us, makes us so wretchedly blind.
