What does the Bible say about the eternality of Christ?

The eternality of Christ is a foundational truth rooted in Scripture, particularly emphasized in John 1:1, which declares, 'In the beginning was the Word.' This verse affirms that Christ, referred to as 'the Word,' was present before the creation began, reinforcing His divine nature and eternal existence. Furthermore, the declaration that 'the Word was God' underscores His equality with the Father in essence and authority. Throughout His earthly ministry, despite taking on human flesh, He remained fully God, revealing this through miracles and teachings that demonstrated His divine power. The understanding of Christ's eternality is vital for grasping the fullness of the gospel and the nature of our relationship with Him.
