Deism is the error, flourishing in the seventeenth and eighteenth centuries among Enlightenment rationalists, that affirms the existence of a Creator God known by reason from the natural order, but denies His providential government, His special revelation, His miracles, and His ongoing involvement in the world. The classic image is the divine clockmaker: God made the universe, wound it up like a great machine, set it to run by fixed natural laws, and then withdrew, leaving it to operate on its own without further intervention. Deism thus retains a remote First Cause while stripping away nearly everything the Scriptures affirm about the living God. It denies providence, holding that God neither preserves nor governs nor cares for His creatures in any active way. It denies miracles and answered prayer, since these would require God to act within His self-running system. It denies special revelation—Scripture, prophecy, the incarnation—insisting that whatever can be known of God is known by reason and nature alone, so that the Bible is at best a republication of natural religion and at worst a fraud. It denies the Trinity, the deity of Christ, and the gospel of redemption, reducing religion to a bare morality and a distant deity. Against all this, Scripture proclaims a God intimately present and active: who upholds all things by the word of His power, in whom we live and move and have our being, who works all things after the counsel of His will, who has spoken by His prophets and supremely in His Son, and who hears and answers the prayers of His people. Deism’s god is an abstraction of philosophy; the God of the Bible is the living Lord of providence and grace.
