The Belgic Confession (Article 1) opens by describing God as 'a single and simple spiritual essence,' eternal, infinite, immeasurable, omnipotent, omniscient, all-good, and infinitely just. God is the Creator, Redeemer, and Sustainer of all things. The CRCNA affirms the classical theistic attributes: God is not dependent on creation, exists necessarily, and is utterly transcendent yet personally knowable through revelation.

A distinctive CRCNA emphasis is God's absolute sovereignty. This sovereignty extends to all events, including the permission of evil. However, God is not the author of sin, and his holy character remains unblemished by the evil that occurs. The CRCNA holds to divine simplicity: God is not composed of parts or accidents; what he has, he is. His justice and love are not distinct properties but one divine reality.

God's sovereignty and goodness together form the foundation of CRCNA piety. Believers are called to trust God's providence in all circumstances, knowing that God works all things together for the good of those who love him. This emphasis on God's active involvement in history — not merely as spectator but as the providential guide — shapes the CRCNA's approach to culture, work, and mission.
