Salvation and Grace:
If you ask 100 people today whether they believe they are saved, you will get a wide range of answers, but that should not be the case. Salvation is a gift of God given freely to all who believe in the atoning work of Christ. "EPH2.8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: EPH2.9 Not of works, lest any man should boast."
Having said that, I should probably take some time to explain what that really means. God being all-knowing made provision from the foundation of the world that Yeshua, the Lamb of God, should offer his life as a sacrifice for the atonement of sin. Sin is the transgression of the law, and the wages of sin is death. Those who sin deserve to die, but thank God for making provision for sinners to be reconciled to God. "HEB9.22 And almost all things are by the law purged with blood; and without shedding of blood is no remission." If a man lives a perfect unblemished life, HE IS RIGHTEOUS. However, since men were not able to fulfill all the requirements of the law, God made provision in the law so that one righteous man could take the place of many sinners. Those who accept God's pardon agree to live for God and to devote their lives to serving him. We do not earn our salvation by serving him: Salvation was given to us freely when we accepted Christ's sacrifice and pardon. The Holy Spirit works with those called by God and helps them along the way to live a Godly life. Living a Godly life is the proof of salvation, not the means by which we are saved. In as much as some of us wish we could be saved by our works, most of us drink iniquity like water, and our own righteous acts cannot save us. Since all men have sinned and fallen short of the glory of God, it is only by grace that a sinner can be saved. Christ being the son of God was able to forgive sins on earth because the Son of Man has power to forgive sins. If he chooses to forgive someone's sins, he does not need to consult anyone. As it is written, "God does not give account of any of his matters to anyone."
So to recap, salvation is not the result of works, but the gift of God given freely to all who truly believe. "ROM11.6 And if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then it is no more grace: otherwise work is no more work."
