The question isn't, Do you have a voice? The question is, Do you have a song? If you've turned from your sins and trusted in the finished work of Christ, if you're forgiven and reconciled to God, then you have a song. It's a song of the redeemed, of those who have been rescued from the righteous wrath of God through the cross of Jesus Christ and are now called his friends. Once we were not a people, but now we are the people of God, and our singing together, every voice contributing, is one way we express that truth.
