This sermon explores the theological concept of divine simplicity, arguing that God is not a composite being made of parts but is wholly and indivisibly Himself. Using the imagery of the moon and the refraction of light through a prism, the message illustrates that God's attributes—such as strength, goodness, and glory—are not separate properties He possesses but are identical to His very being. The text emphasizes that human attempts to domesticate or define God are inherently limited, as the infinite Creator cannot be compressed into finite human understanding. By contrasting the extrinsic nature of human strength with the intrinsic, inexhaustible power of God, the sermon invites believers to awe at the mystery of a God who is always fully present and unchanged. The central call is to abandon the notion of a small, manageable deity and instead rejoice in the boundless, unsearchable greatness of the one who is the source of all life and strength.
