God's Word exhorts us to make music and song an important component of how we worship God and His people have always done so. It helps us make biblical truth beautiful, and memorable. It helps us express our love for God, thanks to God, devotion to God, and dependence upon God.
Psalm 30:4 - "Sing to the Lord, you his faithful ones, and praise his holy name."
Colossians 3:16 - "Let the word of Christ dwell richly among you, in all wisdom teaching and admonishing one another through psalms, hymns, and spiritual songs, singing to God with gratitude in your hearts."
Psalm 150:3-6 - "Praise him with the blast of a ram’s horn; praise him with harp and lyre. Praise him with tambourine and dance; praise him with strings and flute. Praise him with resounding cymbals; praise him with clashing cymbals. Let everything that breathes praise the Lord. Hallelujah!"
Psalm 59:17 - "To you, my strength, I sing praises, because God is my stronghold — my faithful God."
