1 I will sing of the steadfast love of the Lord, forever;
with my mouth I will make known your faithfulness to all generations.
2 For I said, “Steadfast love will be built up forever;
in the heavens you will establish your faithfulness.”
3 You have said, “I have made a covenant with my chosen one;
I have sworn to David my servant:
4 ‘I will establish your offspring forever,
and build your throne for all generations.’ ” Selah
Why do Christians sing? There are really two good answers. Of course we sing to worship our Lord. WE honor him in an act of religious obedience. He commanded it, it pleases him, and we do it.
But there is another reason that we often miss.
Colossians 3:16 – Let the word of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual songs, with thankfulness in your hearts to God.
We sing to teach. We teach one another truth as we sing songs full of truth.
In Psalm 89:1-4, the psalmist says that he will sing of God’s steadfast love and his faithfulness. The psalmist is going to sing lyrics that teach of the chesed, the covenant-making, promise-keeping, never-ending love of God.
Why put this at the beginning? If we do not remember that God’s promising love lasts forever, if we forget that God is always faithful, always true to his promises, we will not be able to handle what comes later in the psalm. We will give up and lose hope when it looks like his promises are too far away to come to pass.
In verse 2, we see that God has established his faithfulness in the heavens. The angels know that God is faithful. The sun, moon, and stars are testimonies to God’s power and consistency. The heavens declare his glory, and part of that declaration is their constant reminder that God is in control and does all he says he will do.
And then in verses 3-4, the psalmist tells us of one promise of God’s. The Lord made a covenant with David. And if God is faithful to his word, he will, he must, keep that promise too.
2 Samuel 7:16 – And your house and your kingdom shall be made sure forever before me. Your throne shall be established forever.’ ”
God promised David that a son of his would build the temple. Solomon did. But God also promised that someone from David’s line, his house, will be established as king forever. A never-ending kingdom will come from David’s line. A king will come who will be king over all. That, of course, is the promise that Messiah, the Christ, will come from David’s family line.
Christians, sing and learn of God’s glory and God’s faithfulness. Sing truth. Sing of the fact that God is always true to his word. Sing and make the Lord known to others. Sing of the kingdom of God and the grace of a God who saves sinners like us. Sing that God fulfilled his promise when he sent his Son. Sing that his promises are still true today.
