A.W. Tozer emphasizes that true spirituality is characterized by deep-seated desires that prioritize holiness over happiness. He argues that many Christians seek happiness instead of striving for holiness, which indicates a lack of true sanctity. Tozer highlights that a genuinely spiritual person seeks to honor God, even at the cost of personal loss or dishonor, embodying a commitment to God's glory that is instinctive and unwavering. This desire for God's glory is as vital as air to a suffocating man, illustrating the depth of longing for divine honor in one's life.
