What does the term 'Lamb of God' signify in Christian theology?

The term 'Lamb of God' signifies not only Christ's sacrificial role but the culmination of the Old Testament sacrifices. In Genesis 22, Abraham's declaration that God would provide Himself a lamb foreshadows Christ’s ultimate sacrifice on the cross. As the true Lamb, Jesus fulfills the requirements laid out in the sacrificial system, offering Himself once for all, which makes Him the perfect and sufficient remedy for sin. Additionally, references in Revelation underscore this imagery by repeatedly recognizing Christ as the Lamb who was slain, reinforcing His role in salvation history.
