There are several reasons why Jesus doesn't need your help to save you, the most obvious is that Jesus has ALREADY reconciled us and the world unto God, 2 Corinthians 5:18, 19. We had nothing to do with God reconciling us and the world unto God, this took place over 2,000 years ago before we were born. It is a past historical event. Jesus as humanities representative fulfilled every jot and tittle of God's holy law, Matthew 5:18. He did this in our name and on our behalf, just like we did it ourselves. The law demands perfection, we don't have it to offer, because we are all born after Adam who was a sinner. We all have Adam's blood flowing through our veins. This is why Paul said, "There is none righteous, no, not one" Romans 3:10. "For all have sinned, and come short of the glory of God" Romans 3:23. Sinners cannot save sinners, nor can sinners save themselves.
Paul wrote, "Therefore by the offense of one (Adam) judgment came upon all men to condemnation: even so by the righteousness of one (Christ) the free gift came upon all men unto justification of life" Romans 518. Just as we were lost by a representative, so we are saved by a representative. We are saved, justified, sanctified and redeemed by the doing and the dying of Jesus. Jesus as our representative and substitute has atoned for our sins and the sins of the whole world, 1 John 2:2.
God requires two things for the salvation of fallen man.
1. A life of perfect obedience according to his holy law.
2. A perfect atonement for our sins and the sins of the whole world.
Jesus in our name and on our behalf, has victoriously met both of these requirements. This why Paul said, "And you are complete in him, which is the head of all principality and power" Colossians 2:10. If we are ALREADY perfect and complete in Christ then what good is religion?
Now, how does this wonderful salvation become ours? It most certainly is not by works, because all of the work of salvation has already been done by Jesus Christ. There is nothing that we can do to add to what Christ has done for us, nor is there anything that we can do to take away from what Christ has done for us. It is a past historical event. All through the Old Testament and into the New Testament God's people are saved and justified by faith. Faith is believing and accepting what God has done for us in Jesus Christ. Even little children are capable of hearing and believing the Gospel.
Holiness theology is anti-Gospel and anti-Christ. The Catholic church and others do not believe the Gospel. They do not believe that Jesus has ALREADY reconciled us and the world unto God. They believe that they can reconcile themselves unto God by their works and obedience to the law. It is a do-it-yourself salvation that is under the judgment of God. Man does not have a righteousness that God will accept, this is why salvation is totally and completely outside of ourselves and is only found in the work and the person of Jesus Christ.
