In Christianity, the cross is the intersection of God’s love and His justice. Jesus Christ is the Lamb of God who takes away the sin of the world. The reference to Jesus as the Lamb of God points back to the institution of the Jewish Passover. The Israelites were commanded to sacrifice an unblemished lamb and smear the blood of that lamb on the doorposts of their homes. The blood would be the sign for the Angel of Death to “pass over” that house, leaving those covered by blood in safety. When Jesus came to John to be baptized, John recognized Him and cried, “Behold, the Lamb of God, who takes away the sin of the world!”, thereby identifying Him and God’s plan for Him to be sacrificed for sin.
One might ask why Jesus had to die in the first place. This is the over-arching message of the Bible—the story of redemption. God created the heavens and the earth, and He created man and woman in His image and placed them in the Garden of Eden to be His stewards on the earth. However, due to the temptations of Satan (the serpent), Adam and Eve sinned and fell from God’s grace. Furthermore, they have passed the curse of sin on to their children so that everyone inherits their sin and guilt. God the Father sent his one and only Son into the world to take on human flesh and to be the Savior of His people. Born of a virgin, Jesus avoided the curse of the fall that infects all other human beings. As the sinless Son of God, He could provide the unblemished sacrifice that God requires. God’s justice demanded judgment and punishment for sin; God’s love moved Him to send His one and only Son to be the propitiation for sin.
Romans 3:23 For all have sinned, and come short of the glory of God; 24 Being justified freely by his grace through the redemption that is in Christ Jesus: 25 Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;
