A.W. Tozer emphasizes the eternal and all-sufficient nature of God, challenging modern individuals to reflect on God's self-existence and the futility of thinking we can contribute to Him through our offerings. He highlights that God is uncreated, eternal, and beyond the constraints of time and space, urging worship and reverence for His infinite nature. Tozer draws inspiration from Frederick William Faber's poetic celebration of God's eternal existence, reminding us that God is the source of all life and cannot be measured by human standards.
