That is the redeeming work, right? Who changes hearts but the Lord? That is his redemption. That is when beauty overcomes selfishness. That is when the good outweighs the evil in all of our hearts. And that is worthy of us saying, “Sing to the LORD a new song, for He has done wonderful things.” And that is worth meditating on.
Why is it a new song that we are singing? What’s the significance of a new song?
Because we are new. In salvation – in that work – we are new creations. We are wholly changed. We are wholly new. And so the songs we sang of selfishness and self-importance and self-indulgence become a song of celebration of His importance and His glory and His works and His perfection instead of ours. So I love the idea of “Sing to the LORD a new song” because the song that any of us are singing apart from Christ is an old song, and it’s a tired song, and it’s not a glory-giving song. And no matter what our story is, until we come to Christ – and apart from coming to Christ – it is not a pretty song. Even if it’s in the church and good deeds, it’s not a pretty song because even that can be about you. And if it’s wild, hard living that’s about your pleasure, so that’s about you too. It doesn’t matter which one it is. Neither one of those give glory to the LORD until we can say, “This is not my life. This is yours. Let it be. You are the source of my song. And you are my song.” And everything apart from that is finite, fleeting, and failing and not glorious and worth singing about at all.
