Are demons real? (Where do they come from? And what do they do?)

Demons are real, and their origin traces back to the Nephilim—the giant offspring of rebellious divine beings and human women—whose disembodied spirits now roam the earth in defiance of God. These unclean spirits emerge from ancient cosmic rebellion and continue to corrupt, deceive, and oppose God’s purposes in the world. They promote false teachings, exploit human institutions, and wage spiritual war against humanity. Yet their influence is not ultimate; through Jesus, the Kingdom of God has broken in to confront and overcome their power.
