A.W. Tozer emphasizes the critical importance of personal holiness in the life of a believer, asserting that it is not merely an option but a divine command rooted in Scripture. He challenges the modern Christian attitude that often dismisses holiness as optional, reminding us that as children of a holy God, we are called to reflect His holiness in our conduct. Tozer acknowledges the struggles believers face in pursuing holiness but assures that God's Spirit provides the strength needed to live a life pleasing to Him. He concludes with a heartfelt prayer for strength and awareness of God's presence in our daily lives.
