Why is it important that Christ gives life?

In John 1:4, it is declared that 'in Him was life, and the life was the light of men.' This gives us a profound understanding that Christ is not merely a teacher or prophet, but the very source of all life. The implications are significant; since the original sin resulted in death—both physical and spiritual—only through Christ can humanity receive regeneration and eternal life. His resurrection symbolizes the life He offers, assuring believers of their own resurrection and eternal existence with Him.
