How do we know Christ's love is evident in His sacrifice?

The love of Christ is profoundly manifest in His sacrificial death on the cross. John 15:13 highlights this by stating that greater love has no one than this, that someone lay down his life for his friends. Throughout the Old Testament, prophecies of the coming Messiah point toward a suffering Savior, and Christ's fulfillment of these prophecies reaffirms God's steadfast love. In His prayer for those who crucified Him—'Father, forgive them; for they know not what they do' (Luke 23:34)—we see a deep compassion and an ultimate act of grace, showcasing His love for mankind. Understanding that Jesus suffered not for His own sins but for those of His people reveals the depth of His love and the intent behind His sacrifice: to atone for sin and secure eternal life for His followers.
