A.W. Tozer emphasizes the profound holiness of God, illustrating that His purity and moral excellence are beyond human comprehension. He reflects on the fallen nature of humanity, which struggles to grasp the concept of true holiness, often settling for a diluted understanding of God's character. Tozer warns against the dangers of a superficial faith that lacks a deep awareness of God's unapproachable holiness, urging believers to recognize their own unworthiness in contrast to God's perfection. He calls for a return to a reverent fear of God, highlighting that without holiness, no one can see the Lord. The sermon concludes with a plea for genuine repentance and a desire for spiritual renewal in the presence of the Holy One.
