5. Blessed is he, etc. As it would not have been enough to reprove the sin, he submits the remedy upon which the proper correction of it depends; and this is, that the hopes of men are only stable and well-founded when they rest entirely upon God. For even the wicked sometimes come the length of acknowledging the folly of trust in man. Accordingly they are often angry with themselves for being so inconsiderate as to expect deliverance from men; but by neglecting the remedy, they are not extricated from their error. The Psalmist having condemned the infatuation, which we have seen to be natural to us all, wisely subjoins that they are blessed who trust in God. Jeremiah observes the same order. (Jeremiah 17:5, 7.)

“Cursed is he that trusteth in man, and maketh flesh his arm,” etc.;

and then — “Blessed is the man whose hope the Lord is.” When David pronounces those blessed whose help is the Lord, he does not restrict the happiness of believers to present sense, as if they were only happy when God openly and in outward acts appeared as their helper, but he places their happiness in this — that they are truly persuaded of its being entirely by the grace of God they stand. He calls him the God of Jacob, to distinguish him from the multitude of false gods in which unbelievers gloried at that time; and there was good reason for this; for while all propose to themselves to seek God, few take the right way. In designating the true God by his proper mark, he intimates that it is only by an assured faith of adoption that any of us can rest upon him; for he must show himself favorable to us before we can look for help from him.
