Christians believe that the death of Jesus paid for our sin.
We believe that Jesus helped us to find our way back to our faith, by being a substitute and standing in for God by making a bridge between us and him. It was easier that way for him to reconcile us and make us understand. Through atonement for our sins, he helped us regain the love and salvation of our Lord.
It was very important for Jesus to show us that he was the son of God, and not only fully human, but fully divine as well. He also needed to show us that he could take our burdens with him to the cross and die for our sin, before rising and releasing us from the grasp of our afflictions. It was also very necessary for him to do what he did, because someone who was perfect had to put things right, Jesus was not perfect God was perfect, but through Jesus, God worked!.
There are lots of stories told that are of people who put their lives forward to save someone else from death. In the textbook there is the story of the soldier who died in the place of another man, even though the soldier had not done anything at all, however, he owned up to this crime to save the life of another man.
"For the son of man himself came not to be served but to give his life as a ransom for many" Mark- 10.45.
This quotation from Marks Gospel clearly states that Jesus did not come down to earth to be treated as a king, but as an ordinary man. .
'A sacrifice is an offering of something highly valued for the sake of someone considered to have higher/greater value or claim.' (Quote from oxford English dictionary.).
For someone with the wisdom, courage and holiness, that Jesus had, to give up all that for people who had sinned against God, was such a obeisant and compassionate thing to do for his people. Jesus was vindicated by God through his death to prove how much he loved his people by sacrificing his only son to redeem us from sin.
The lord always shows mercy to people who show that they are sorry through the sacrament of reconciliation, where God shows expiration.
