The sermon unfolds a profound meditation on the incomprehensible greatness of God as revealed in the Westminster Confession of Faith, emphasizing His aseity, self-sufficiency, sovereignty, omniscience, and holiness. It establishes that God exists independently, possesses all life, glory, goodness, and blessedness in Himself, and requires nothing from creation, yet freely chooses to reveal Himself in grace and covenant. His sovereignty over all things—creation, providence, and history—demands worship, as every creature, from angels to humanity, is called to glorify Him. The sermon culminates in a call to worship, rooted in awe at God's unsearchable nature, urging believers to live in continual praise, recognizing that all glory belongs to Him alone, and that the ultimate purpose of life is to glorify and enjoy God forever.
