What does the Bible say about the new song in Psalm 144?

Psalm 144:9 states, 'I will sing a new song unto thee, O God.' This new song symbolizes the transformation that occurs in the hearts of those whom God regenerates. In Psalm 40:2-3, we see a similar sentiment, where the Lord brings us out of our sinful nature and places a new song in our mouths, one that praises His glorious works in saving His people. This theme of a new song continues through Scripture, as it highlights that our praise is not based on our merit but rather on what God has accomplished through Christ.
