“I will sing of the mercies of the LORD for ever: with my mouth will I make known Thy faithfulness to all generations.” Psalm 89:1 (KJV)
A Maschil of Ethan the Ezrahite is the title of this Psalm. A song of instruction; and surely there is not much else to sing of than of the LORD and His mercy.
The mercy of the LORD is everlasting. There is another of the Psalms which magnifies the mercy of the LORD. Psalm 136 has every verse ending with “For His mercy endureth forever”. The mercies of God. Let that be your song for today.
Part of His mercies is also that He is faithful. He is faithful to every generation. He is faithful to all the earth, and to all His creation. He is faithful to His own glory, power and praise.
Sing a song today; and let it be a song of His mercies. The greatest display of His mercy was by the judgment of His Son Jesus on the cross for your sins and mine.
