God tells Israel to sing when she is barren (Isaiah 54:1). This is not because He is cruel, but because He knows something we don’t know—that our praise is the signal He waits for to release His grace more abundantly, particularly praise forthcoming when all hope seems lost (Romans 4:18). We are a “royal priesthood” (1 Peter 2:9), and that means our warfare is of a peculiar kind that is only effective when worship goes ahead of us into battle. The restoration of the dominion of the children of God over the earth under Christ our Head is related to constancy in worship. Nothing advances without praise.
