Major Ian Thomas emphasizes that the unique human spirit allows man to receive the Holy Spirit, enabling divine behavior as intended by God. He explains that true faith is an attitude of total dependence on God, which is essential for pleasing Him and behaving as He intended. Thomas argues that without the Holy Spirit, man cannot fulfill his purpose and is left to function merely as an animal, devoid of divine influence. He stresses that faith must be active and expressed through obedience, as anything less is considered sin. Ultimately, the sermon calls for a deeper understanding of faith and the necessity of the Holy Spirit in restoring humanity to its intended state.
