The sermon centers on the question of justification, exploring why we, as worshippers, have the right to approach God. It argues that true vindication isn's found in personal integrity or moral perfection, but rather through faith in Jesus Christ, whose righteousness and mercy provide access to God's presence. Drawing from Psalm 26, the message emphasizes the need for humility, a recognition of our sinfulness, and a constant seeking of God's grace, ultimately leading to a deeper appreciation for the holiness of worship and a longing for the day when we will see Christ face to face.
