The "Historical Gospel" of Jesus Christ is the most significant event in the history of the world. Just before Jesus died on the cross he said, "It is finished" John 19:30. What did Jesus mean when he said that? What Jesus meant is that all of the requirements for the salvation of fallen man had been met. What were the requirements that were required for the salvation of fallen man? God requires,
1. A life of perfect obedience according to God's Holy Law.
2. A perfect atonement for the sins of man and for the whole world.
While Jesus was dying on the cross, God tore the veil that covered the "Holy of Holies" on the Jewish temple, from the top to the bottom, Matthew 27:51. This signified the end of the Old Covenant, the law and the Jewish religion. Jesus had victoriously met all of God's requirements and conditions for the salvation of fallen man and in doing so reconciled fallen man and the world unto God.
"And all things are of God, who has reconciled us to himself by Jesus Christ and has given unto us the ministry of reconciliation (which is the Gospel) 2 Corinthians 5:18.
"To wit that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them and has committed unto us (Christians) the ministry of reconciliation" (which is the Gospel) 2 Corinthians 5:19.
Every jot and tittle of God's Holy Law has been fulfilled and met, Matthew 5:18. Every sin that had ever been committed or will be committed has been atoned for, 1 John 2:2. Because of the victorious work of Jesus on behalf of fallen man, God has made Jesus both Lord and Christ, Acts 2:36 and has seated Jesus at his own right hand, which is a place of honor and respect, Hebrews 1:3.
"It is finished and Jesus is Lord" Because all of the work of salvation has been accomplished by Jesus Christ, there is nothing left for fallen man to do, other than to live by faith in Christ and his Gospel, Romans 1:17. We who believe this Gospel have entered into God's rest.
"For he that has entered into his rest, he also has ceased from his own works (religion) as God did from his" Hebrews 4:10.
Jesus is God's justifier, sanctifier and redeemer, 1 Corinthians 1:30. This is why Paul could say, "And you are complete in him, which is the head of all principality and power" Colossians 2:10.
