Why is the concept of Jesus' eternality important for Christians?

Understanding that Jesus is eternal and identified as 'I Am' is foundational to Christian faith. This truth confirms that Christ is not just a historical figure but the eternal Son of God who has always existed with God the Father. His statement in John 8:58, asserting His existence before Abraham, encapsulates this truth. It reassures believers that Jesus is reliable and unchanging amidst temporal and fleeting circumstances. Furthermore, as believers, we can find hope in the promise of eternal life through faith in Him, knowing He has authority over death and can grant life.
