Jesus’ ministry on earth began when he was declared by John the Baptist to be, “the Lamb of God, who takes away the sin of the world!” (John 1:29). After Jesus was baptized, Matthew tells us that a voice from heaven said, “This is my beloved Son, with whom I am well pleased” (Matthew 3:17). Not long before he was crucified, Jesus revealed to his disciples his purpose for coming to earth. Jesus told them, “You know that the rulers of the Gentiles lord it over them, and their great ones exercise authority over them. It shall not be so among you. But whoever would be great among you must be your servant, and whoever would be first among you must be your slave, even as the Son of Man came not to be served but to serve, and to give his life as a ransom for many” (Matthew 20:25-28). The Greek word that is translated ransom, Lutron (looˊ-tron) is “used metaphorically for the ransom paid by Christ for the delivering of men from the bondage of sin and death (Matthew 2);28; Mark 10:45)” (G3083). Paul explained in his first letter to Timothy that Jesus was acting as a mediator between God and man when he died for the sin of the world. Paul said we should pray for all people because, “This is good, and it is pleasing in the sight of God our Savior, who desires all people to be saved and to come to the knowledge of the truth. For there is one God and there is one mediator between God and men, the man Christ Jesus, who gave himself as a ransom for all, which is the testimony given at the proper time” (1 Timothy 2:3-6),

Jesus compared his position as the Son of Man to that of a slave (Matthew 20:27-28). Jesus served his Father and mankind by coming to earth to reconcile all people to God. In this relationship of servitude, Jesus was one whose will was completely subject to the will of another, the lowest term in the scale of servitude. A mediator, as a go-between, is “one who intervenes between two parties” (G3316). It was necessary for Jesus to intervene between God and mankind because of the wrath of God against sin. Paul said in his letter to the Romans, “For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men” (Romans 1:18). Paul indicated that God’s kindness is meant to lead people to repentance and then, went on to say, “But because of your hard and impenitent heart you are storing up wrath for yourself on the day of wrath when God’s righteous judgment will be revealed” (Romans 2:4-5). Jesus took the wrath of God upon himself through his death on the cross. It says in Isaiah 53:5, “But he was pierced for our transgressions, he was crushed for our iniquities, upon him was the chastisement that brought us peace, and with his wounds we are healed.” Speaking of God’s eternal covenant of peace, Isaiah’s prophecy about Jesus’ crucifixion states, “’For a brief moment I deserted you, but with great compassion I will gather you. In overflowing anger for a moment I hid my face from you, but with everlasting love I will have compassion on you,’ says the LORD, your Redeemer” (Isaiah 54:7-8).  

Paul explained that God’s love for humanity was expressed by him sending his Son to die for individuals that didn’t deserve his forgiveness. Paul said:

For while we were still weak, at the right time, Christ died for the ungodly. For one will scarcely die for a righteous person though perhaps for a good person one would dare even to die, but God shows his love for us in that while we were still sinners, Christ died for us. Since, therefore, we have now been justified by his blood, much more shall we be saved by him from the wrath of God. For if while we were enemies we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life. More than that, we also rejoice in God through our Lord Jesus Christ, through whom we have now received reconciliation. (Romans 5:6-11)

Paul identified reconciliation as the means by which peace with God is accomplished. The Greek word that is translated reconciliation, katallage (kat-al-lag-ayˊ) means “exchange (figurative, adjustment), i.e. restoration to (the divine) favor” (G2643). To be reconciled means that we change toward God, we are no longer considered to be his enemies (G2644). Peace with God means “metaphorically, peace of mind, tranquility, arising from reconciliation with God and a sense of divine favor (Romans 5:1; 15:13; Philippians 4:7 [cf. Isaish 53:5])” (G1515).

Paul explained that the reason why Jesus’ righteousness could be attributed to sinners was because Adam’s sin was attributed to everyone who was born after him. Paul said, “Therefore, as one trespass led to condemnation for all men, so one act of righteousness leads to justification and life for all men. For as by the one man’s disobedience the many were made sinners, so by the one man’s obedience the many will be made righteous” (Romans 5:18-19). Paul expanded on his explanation of Christ’s work of reconciliation in his second letter to the Corinthians. Paul stated, “Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold the new has come. All this is from God, who through Christ reconciled us to himself and gave us the ministry of reconciliation: that is, in Christ God was reconciling the world to himself, not counting their trespasses against them, and entrusting to us the message of reconciliation. Therefore, we are ambassadors for Christ, God making his appeal through us. We implore you on behalf of Christ, be reconciled to God. For our sake he made him to be sin who knew no sin, so that in him, we might become the righteousness of God” (2 Corinthians 5:17-21).

Jesus concluded his ministry on earth with a statement about having overcome the world. After his disciples indicated that they believed he came from God, Jesus answered them, “Do you now believe? Behold, the hour is coming, indeed it has come, when you will be scattered, each to his own home, and will leave me alone. Yet I am not alone, for the Father is with me. I have said these things to you, that in me you may have peace. In the world you will have tribulation. But take heart; I have overcome the world” (John 16:31-33). Jesus may have made reference to his disciples deserting him because he wanted them to be aware that his work of reconciliation was still incomplete, even though he stated that he had already overcome the world. It wasn’t until his disciples were justified by faith that they obtained access into God’s grace and peace with God was possible. Regarding his death and resurrection, Jesus said, “I have told you before it takes place, so that when it does take place you may believe” (John 14:29). When Jesus’ disciples believed, they were justified by faith and afterward, had peace with God (Romans 5:1).
