Will there be music and singing in New Jerusalem? Revelation 21–22 does not answer this question, but a broad view of the Bible says YES. The conclusion of the Psalms, Psalm 150, urges us to praise God and to praise Him with many musical instruments, even with loud music and dancing. The conclusion of the Bible should be the same.
Psalm 150 begins, “Hallelujah! Praise God in His sanctuary.” God’s eternal sanctuary, His eternal tabernacle and temple, is New Jerusalem.
Hebrews 2:12, quoting Psalm 22, is a declaration of the resurrected Lord Jesus, “I will declare Your [the Father’s] name to My brothers; in the midst of the church I will sing hymns of praise to You.”
The Lord sings praise to God the Father now in and through the church and we expect this to continue eternally in New Jerusalem. Romans 15:9 is similar; the Lord says, “I will sing praise to Your name.”
Ephesians 5 and Colossians 3 present the proper Christian life, including “singing and psalming with your heart to the Lord” and “singing with grace in your hearts to God.” Will this not continue eternally?
Revelation 5:8-9, 14:2-3, and 15:2-3 describe heavenly music, singing, praising God for His person and for His accomplishments. All the music and singing in New Jerusalem will be heavenly. None will be of the earthly nature common in today’s concerts. And all the music will glorify God. Praise Him!
