Praise him with the sounding of the trumpet,
praise him with the harp and lyre,
praise him with tambourine and dancing,
praise him with the strings and flute,
praise him with the clash of cymbals,
praise him with resounding cymbals.
Let everything that has breath praise the LORD.
Praise the LORD.
While I believe “worship wars” as I like to refer to them have died down some now, people still get worked up over what instruments are acceptable in a church setting. This usually has more to do with personal preference than what is truly acceptable but it is presented as if something is sacred about whatever preferences a person has. And yes, it goes both ways – “We need guitar to reach out to young people,” and “The church shouldn’t have drums, we’re not putting on a show” are two common complaints.
We don’t necessarily use the harp and flute in our worship today, but it is acceptable to do so. Psalm 150 lists probably all of the instruments available at the time. The point is that we’re to praise the Lord and use every means necessary.
Instruments are cultural. Some instruments are not going to fit within a certain culture. The kettle drums or bagpipes probably aren’t going to go over well in your church but there would be nothing wrong with them in Jamaica and Scotland.
If you have a preference for the guitar, drums, piano, or organ, that’s great. Don’t make any of them sacred however. The church should be focusing on reaching the lost, not arguing over what instruments are proper within the walls of the church.
