Psalms 23:6

For this is the final perfection of all good things.… "The house of the Lord indicates the Jerusalem to come, which endures "for the length of days," without uncertainty, for it is an enduring blessedness and a joy that never ends.

When do you not have something that you owe to God? Or when are you without a gift of God, since your daily enjoyment of living is from God? "For what have you, that you have not received?" Therefore, because you always receive, always call on God; and since what you have is from God, always acknowledge that you are his debtor. I prefer that you pay your debts rather through love than as one forced to do so.

"And your mercy," etc. Here he sets forth future benefits. And first, with regard to participation in divine gifts; second, with regard to the enjoyment of God Himself. He says therefore: you have done all these aforementioned things for me; but I ask that "your …

We are saved by hope, and that hope will not make us ashamed, because it is well grounded. It is the duty of Christians to encourage themselves in the Lord their God; and we are here directed to take that encouragement both from the relation wherein he stands to us and from the experience we have had of his goodness according to that relation.

His hope rises, and his faith is strengthened, by being exercised. Observe, (1.) What he promises himself--goodness and mercy, all the streams of mercy flowing from the fountain, pardoning mercy, protecting mercy, sustaining mercy, supplying mercy.

Surely goodness and mercy shall follow me,....

"Surely goodness and mercy shall follow me all the days of my life." This is a fact as indisputable as it is encouraging, and therefore a heavenly verily, or "surely" is set as a seal upon it. This sentence may be read, "only goodness and mercy," for there shall be unmingled mercy in our history. These twin guardian angels will always be with me at my back and my beck. Just as when great princes go abroad they must not go unattended, so it is with the believer. Goodness and mercy follow him always— "all the days of his life" —the black days as well as the bright days, the days of fasting as well as the days of feasting, the dreary days of winter as well as the bright days of summer. Goodness supplies our needs, and mercy blots out our sins. "And I will dwell in the house of the Lord for ever.""A servant abideth not in the house for ever, but the son abideth ever." While I am here I will be a child at home with my God; the whole world shall be his house to me; and when I ascend into the upper chamber, I shall not change my company, nor even change the house; I shall only go to dwell in the upper storey of the house of the Lord for ever. May God grant us grace to dwell in the serene atmosphere of this most blessed Psalm!

Goodness and mercy shall follow me - As I pass on through the vale of life, thy goodness and mercy shall follow my every step; as I proceed, so shall they. There seems to be an allusion here to the waters of the rock smitten by the rod of Moses, which followed the Israelites all the way through the wilderness, till they came to the Promised Land. God never leaves his true followers providential mercies gracious influences, and miraculous interferences, shall never be wanting when they are necessary. I will dwell in the house, ושבתי veshabti, “and I shall Return to the house of the Lord,” for ever, לארך ימים leorech yamim, “for length of days.” During the rest of my life, I shall not be separated from God’s house, nor from God’s ordinances; and shall at last dwell with him in glory. These two last verses seem to be the language of a priest returned from captivity to live in the temple, and to serve God the rest of his life.

Surely goodness and mercy shall follow me - God will bestow them upon me. This is the “result” of what is stated in the previous verses. The effect of God’s merciful dealings with him had been to lead his mind to the assurance that God would always be his shepherd and friend; that He would never leave him to want. All the days of my life - Through all its changes; in every variety of situation; until I reach its close. Life indeed would end, and he does not venture to conjecture when that would be; but as long as life should continue, he felt confidently assured that everything needful for him would be bestowed upon him. The language is the utterance of a heart overflowing with joy and gratitude in the recollection of the past, and full of glad anticipation (as derived from the experience of the past) in regard to the future. And I will dwell in the house of the Lord for ever - Margin, as in Hebrew: “to length of days.” The expression, I think, does not refer to eternity or to heaven, but it is parallel with the former expression “All the days of my life;” that is, he would dwell in the house of the Lord as long as he lived - with the idea added here, which was not in the former member of the sentence, that his life would be long, or that he hoped and anticipated that he would live long on the earth. The phrase used here, “I will dwell in the house of the Lord,” is one that is several times employed in the Psalms as indicative of the wish of the psalmist. […]
