A.W. Tozer emphasizes the necessity of experiencing truth rather than merely knowing it, warning against the dangers of religious complacency that can hinder spiritual growth. He points out that those who believe they have 'arrived' may miss out on deeper truths and experiences of God, as seen in the lives of great saints who were driven by a profound yearning for God. Tozer encourages believers to continue praying, fighting, and singing, urging them to press on into the deeper things of God while remaining grounded in their faith.
