Why is it that Christians sing in worship? Christianity has produced centuries of music — high music, low music, middle music, happy music, sad music. Songs of worship and songs of gladness and songs of lament. Everywhere Christianity goes, God’s people sing. Why? We sing because our God is a God of grace. We sing, not only in response to his lavish grace — we sing because it is a means of God’s grace. We sing because singing is a God-given weapon against our greatest enemy.
