Charles H. Spurgeon on Psalms 89:1

Whole Psalm. The present Psalm makes a pair with the preceding one. It is a spiritual Allegro to that Penseroso...That Psalm was a dirge of Passion Tide, this Psalm is a carol of Christmas. —Christopher Wordsworth.

Whole Psalm. There are many passages in this Psalm which do clearly evidence that it is to be interpreted of Christ; yea, there are many things in this Psalm that can never be clearly, pertinently, and appositely applied to any but Jesus Christ. For a taste, see Ps 89:19 "I have laid help upon one that is mighty", mighty to pardon, reconcile, to justify, to save, to bring to glory; suitable to that of the Apostle, Heb 7:25, "He is able to save to the uttermost" —that is, to all ends and purposes, perfectly, completely, fully, continually, perpetually. Christ is a thorough Saviour, a mighty Saviour: Isa 63:1, "Mighty to save." There needs none to come after him to finish the work which he hath begun: Ps 89:19, I have exalted one chosen out of the people, which is the very title given to our Lord Jesus: Isa 62:1, "Behold my servant, whom I uphold; mine elect", or chosen one, "in whom my soul delighteth": Ps 89:20, I have fouled David my servant. Christ is very frequently called by that name, as being most dearly beloved of God, and most highly esteemed and valued by God, and as being typified by him both as king and prophet of his church: Ps 89:20, With my holy oil have I anointed him; suitable to that of Christ; Lu 4:18, "The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor"; and therefore we need not doubt of the excellency, authority, certainty, and sufficiency of the gospel: Ps 89:27, I will make him my firstborn, higher than the kings of the earth. Christ is the firstborn of every creature, and in all things hath the preeminence: Ps 89:29, His seed also will I make to endure for ever, and his throne as the days of heaven. This is chiefly spoken of Christ and his kingdom. The aspectable heaven is corruptible, but the kingdom of heaven is eternal; and such shall be Christ's seed, throne and kingdom: Ps 89:36, His seed shall endure for ever, and his throne as the sun before me. "Christ shall see his seed, he shall prolong his days, and the pleasure of the LORD shall prosper in his hand", Isa 53:10. And his throne as the sun before me; that is, perpetual and glorious, as the Chaldee explains it, shall shine as the sun. Other kingdoms and thrones have their times and their turns, their rise and their ruins, but so hath not the kingdom and throne of Jesus Christ. Christ's dominion is "an everlasting dominion", which shall not pass away; "and his kingdom that which shall not be destroyed", Da 7:13-14. I might give further instances out of this Psalm, but enough is as good as a feast. New saith God, "I have made a covenant with him; "so then there is a covenant that God the Father hath made with Christ the Mediator; which covenant, the Father engages to the Son, shall stand fast, there shall be no cancelling or disannulling of it. God the Father hath not only made a covenant of grace with the saints in Christ, but he has also made a covenant of redemption, as we call it for distinction sake, with Jesus Christ himself: "My covenant shall stand fast with him; " that is, with Christ, as we have fully demonstrated. —Thomas Brooks.

This one short verse contains the summary, pith, and argument of the whole long Psalm; wherein observe The Song's Ditty, the lovingkindness and truth of the Lord, manifested unto the whole world generally, to David's house (that is, the church) especially. The Singer's Duty, magnifying the mercies of God always, even from one generation to another. And by all means; with his mouth, for that is expressed in this verse; with his mind, for that is implied in the next —I have said, etc., that is, believed in my heart, and therefore spake it with my tongue, Ps 116:10. "For out of the heart's abundance the mouth speaketh", Mt 12:34. —John Boys.
