14 Deliver me from the guilt of bloodshed, O God,
you who are God my Savior,
and my tongue will sing of your righteousness. Psalm 51:14
There’s no question that David knew what he did was wrong. He would have to live with that decision the rest of his life. Could he have been punished by the courts of his day? Yes, but it was unlikely, well, because he was king. Consider the sin Amnon committed later (2 Samuel 13:22 – 14:24) and what the courts did about it: nothing.
David knew that the memory of his sins had the potential to be burdensome, so he asked to be delivered from that guilt.
The last half of the verse is in direct contrast to the first. The righteousness of God was met in Christ’s work on the cross. Even thousands of years before Christ came, David knew of that righteousness. He knew it because he experienced it.
Today is just a good day to sit back and reflect on what God has done for us. On the one hand we see our sin, our utter reckless lives. But on the other is Christ, our righteousness.
That is something to sing about.
