What does the Bible say about the only true God?

The Bible, particularly in 1 Kings 18, emphasizes the sovereignty and uniqueness of God as Elijah confronts the false prophets of Baal. Elijah’s prayer is a plea for the people to recognize the Lord as the only true God. This theme is reinforced in Jesus’ words in John 17:3, where He defines eternal life as knowing 'the only true God, and Jesus Christ whom Thou hast sent.' The concept of God being the only true deity is foundational in scripture and encapsulates His sovereignty, holiness, and justice, which are central to the Christian faith.
