The psalmists, including David, provide a preview of heaven for us. Twice in the Book of Revelation we are reminded the redeemed gathered around the throne of the Lamb sang a new song. (Revelation 5:9; 14:3) Five times we are informed by the psalmists a new song was being sung. (Psalms 33:3; 40:3; 96:1; 98:1; 144:9) David indicated God had placed this new song in his mouth which was a hymn of praise to God. This song would enable many to see and understand who God is and what He had done so people would come to trust Him. (Psalm 40:3) Psalm 98 highlighted the fact God had performed marvelous deeds including salvation and deliverance. (Psalm 98:1) Furthermore God has made known His salvation to the entire world. (Psalm 98:2)
As children of God we believe God has placed a new song in our hearts as a result of the amazing work He has carried out in us. We who were dead in our sins have been made alive in Him. Since we are in Christ, we understand God has made us a new creation in Him. (II Corinthians 5:17) The life and the newness this life in Christ entails are why we have something to sing about. We have been cleansed, forgiven and made into a new creation in Him. We have a new song–a song of joy–placed in our hearts by virtue of the work God has done in us through Christ. We even know “when we’ve been there ten thousand years, bright shining as the sun, we’ve no less days to sing God’s praise than when we’ve first begun.” (Amazing Grace) The new song of the Psalms and Revelation will never grow old as it is as current and fresh as the One to whom we will sing it.
