A.W. Tozer explores the concept of 'wonder' as the third stage of true worship, emphasizing that it transcends understanding and leads to a delightful astonishment in the presence of God. He cites biblical figures like Abraham, Moses, Paul, and John, who experienced profound awe during their encounters with the divine, illustrating that such wonder is a timeless aspect of worship. Tozer acknowledges that while these experiences may seem extraordinary, the spiritual essence remains constant for all believers. He highlights the role of hymns in expressing this wonder, suggesting that they capture the ineffable feelings of worshipers. Ultimately, Tozer indicates that while wonder is significant, it is not the final stage of worship, as true adoration must follow.
