What is the significance of Jesus being called the Lamb?

The term 'Lamb' underscores Jesus' fulfillment of the sacrificial system established in the Old Testament. Throughout Scripture, lambs were used as offerings for sin, representing the need for a perfect substitute. Jesus embodies this role, as affirmed in passages such as John 1:29 and Matthew 1:21, where He is identified as the one who will save His people from their sins. This highlights the gravity of His mission and the depth of God's love for His elect, as He willingly became the sacrifice to reconcile sinners to Himself.
