What does the Bible say about the eternity of Jesus?

The concept of Jesus' eternity is made clear in the Gospel of John, specifically in John 8:58, where Jesus states, 'Before Abraham was, I am.' This declaration not only asserts His existence prior to Abraham but also employs the divine name attributed to God in the Old Testament, indicating that Jesus is indeed God. Furthermore, this statement underlines the eternal nature of Jesus, emphasizing that He is not bound by time or created existence. The implications of this truth resonate throughout Scripture, confirming His divinity and sovereignty over all creation, as found in Colossians 1:16 which declares that 'by him all things were created.'
