Why is it significant that Christ laid down His life for us?

In John 15:13, Jesus states that the greatest love is shown when a person lays down their life for their friends. This act of self-sacrifice is what He accomplished through His crucifixion, providing redemption for all believers. By willingly offering Himself, He secured our justification and reconciliation with God, emphasizing that it cost the same price for Christ to redeem each of us. This profound act encourages us to love one another deeply, reflective of His love for us as members of His body.
