The Spirit of God is always the spirit of liberty; the spirit that is not of God is the spirit of bondage, the spirit of oppression and depression. The Spirit of God convicts vividly and tensely, but He is always the Spirit of liberty. God who made the birds never made birdcages; it is men who make birdcages, and after a while we become cramped and can do nothing but chirp and stand on one leg. When we get out into God's great free life, we discover that that is the way God meant us to live "the glorious liberty of the children of God."
