A.W. Tozer explores the three degrees of divine knowledge in his sermon 'The Knowledge of God 2', emphasizing that knowledge of God can be attained through reason, faith, and spiritual experience. He explains that nature reveals God's eternal power and Godhead, as seen in Romans 1:19-20, and that the Holy Spirit provides deeper understanding beyond what reason and faith can offer. Tozer illustrates how the natural world teaches us about God's existence, omnipotence, omniscience, and care for creation, ultimately leading to the conclusion that all creation reflects the divine. He encourages believers to recognize the theological insights nature provides while preparing to discuss the next degree of knowledge revealed through faith in the following sermon.
