Music by way of singing and playing instruments is only a small fraction of the true essence of worship. More than that, worship consists in living a lifestyle that pleases and honors God. This is not to discredit singing hymns of praise and worship to God because that also plays a vital role in the life of a believer.
But adoration goes beyond the songs we sing:
So whether you eat or drink or whatever you do, do it all for the glory of God.
1 Corinthians 10:31
The glory of God must be the goal of everything we do. We can worship God even when we do not have a guitar or access to a playlist in iTunes.
