Psalm 98, often associated with Isaac Watts' famous Christmas carol "Joy to the World," is a triumphant declaration of God's salvation and promise to set the world right. Written by David, it celebrates God's love and His ultimate return to restore creation. The psalm invites all of nature, from oceans to mountains, to praise God for His undying love and justice. Isaac Watts transformed it into a hymn not just for Christ's birth but for His second coming, symbolizing the end of sin and the curse. This powerful message of grace and forgiveness highlights the victory of God's love over sin.
