2 Praise Him for His mighty acts; Praise Him according to His excellent greatness! 3 Praise Him with the sound of the trumpet; Praise Him with the lute and harp! 4 Praise Him with the timbrel and dance; Praise Him with stringed instruments and flutes! 5 Praise Him with loud cymbals; Praise Him with clashing cymbals! (Psalm 150:2–5, NKJV)
The question is posed, “Why shouldn’t we use instrumental music to worship God today? After all, they were used by Israel in the Old Testament.” Yes, they were. Scripture says king Hezekiah “stationed Levites in the house of the Lord with cymbals, with stringed instruments, and with harps, they were commanded “according to the commandment of David, of Gad the king’s seer, and of Nathan the prophet; for thus was the commandment of the Lord by His prophets” (2 Chronicles 29:25). But, we do not live under the authority of the old covenant. We hear and follow Christ for our approved worship, not Moses and the prophets (Matthew 17:1-5; Hebrews 1:1-2). We would not think of binding the Levitical rituals of worship, including animal sacrifices, today. Yet, king Hezekiah did along with the instruments he set in place (2 Chronicles 29:26-36). If Hezekiah’s trumpets and stringed instruments are allowed in worship today, then so are his animal sacrifices and associated offerings. We are content with the musical worship Christ revealed and approved in the new covenant. It repeatedly says to sing praises to God, but never to play praises (Ephesians 5:19; Colossians 3:16). That’s enough.
