The Covenant of God Can't Be Broken
Psalm 89
I will sing of the Mercies of the LORD for ever: with my mouth will I make known Your faithfulness to all generations. (Williams says, “The Messiah, in the confidence of Coronation and of the fulfillment of the sure Promises made to Him as David [Acts 13:34], recites these Promises, voices the lament of His people at their seeming breach, and then closes the Psalm as He began it, with praise to Jehovah.
Thus, during His life of sorrow, His death of shame, and His arrest in Sheol, nothing is seen in Him but perfection—perfection of faith toward God and of love toward man.”)
2 For I have said, Mercy shall be built up for ever: Your faithfulness shall You establish in the very heavens. (The Law came by Moses, but Grace and Truth came by Jesus Christ [Jn. 1:17].)
3 I have made a Covenant with My chosen, I have sworn unto David My servant.
4 Your seed will I establish for ever, and build up your throne to all generations. Selah. (II Sam., Chpt. 7, records the Davidic Covenant, promising David an Eternal Seed and Throne. Jesus Christ is the Root of David and will reign supremely forever. That was the intention of the Davidic Covenant, and it will yet be realized.)
5 And the Heavens shall praise Your wonders, O LORD: Your faithfulness also in the congregation of the Saints. (This Chapter is replete with the “faithfulness” of God. The word occurs seven times [Vss. 1, 2, 5, 8, 24, 33, 49]. Actually, the word “lovingkindness” in Verse 49 could have been translated “faithfulness.”)
