Psalm 23:6 (ESV) … “Surely goodness and mercy shall follow me all the days of my life, and I shall dwell in the house of the Lord forever.”
Surely goodness and mercy. Having recounted the blessings which God had bestowed upon him, he now expresses his undoubted persuasion of the continuance of them to the end of his life. But whence proceeded this confidence, by which he assures himself that the beneficence and mercy of God will accompany him forever, if it did not arise from the promise by which God is accustomed to season the blessings which he bestows upon true believers, that they may not inconsiderately devour them without having any taste or relish for them?
When he said to himself before, that even amidst the darkness of death he would keep his eyes fixed in beholding the providence of God, he sufficiently testified that he did not depend upon outward things, nor measured the grace of God according to the judgment of the flesh, but that even when assistance from every earthly quarter failed him, his faith continued shut up in the word of God. Although, therefore, experience led him to hope well, yet it was principally on the promise by which God confirms his people with respect to the future that he depended.
If it is objected that it is presumption for a man to promise himself a continued course of prosperity in this uncertain and changing world, I answer, that David did not speak in this manner with the view of imposing on God a law; but he hoped for such exercise of God’s beneficence towards him as the condition of this world permits, with which he would be contented. He does not say, My cup shall be always full, or, My head shall be always perfumed with oil; but in general he entertains the hope that as the goodness of God never fails, he will be favourable towards him even to the end.
I will dwell in the house of Jehovah. By this concluding sentence he manifestly shows that he does not confine his thoughts to earthly pleasures or comforts; but that the mark at which he aims is fixed in heaven, and to reach this was his great object in all things. It is as if he had said, I do not live for the mere purpose of living, but rather to exercise myself in the fear and service of God, and to make progress daily in all the branches of true godliness. He makes a manifest distinction between himself and ungodly men, who take pleasure only in filling their bellies with luxuriant fare. And not only so, but he also intimates that to live to God is, in his estimation, of so great importance, that he valued all the comforts of the flesh only in proportion as they served to enable him to live to God.
He plainly affirms, that the end which he contemplated in all the benefits which God had conferred upon him was, that he might dwell in the house of the Lord. Whence it follows, that when deprived of the enjoyment of this blessing, he made no account of all other things; as if he had said, I would take no pleasure in earthly comforts, unless I at the same time belonged to the flock of God, as he also writes in another place, “Happy is that people that is in such a case: yea, happy is that people whose God is the Lord,” (Psalm 144:15.)
Why did he desire so greatly to frequent the temple, but to offer sacrifices there along with his fellow-worshippers, and to improve by the other exercises of religion in meditation upon the celestial life? It is, therefore, certain that the mind of David, by the aid of the temporal prosperity which he enjoyed, was elevated to the hope of the everlasting inheritance. From this we conclude, that those men are brutish who propose to themselves any other felicity than that which arises from drawing near to God.
