Galatians 2: 21 says,
"We ourselves are Jews by birth and not Gentile sinners; yet we know that a person is not justified by works of the law but through faith in Jesus Christ, so we also have believed in Christ Jesus, in order to be justified by faith in Christ and not by works of the law, because by works of the law no one will be justified.
But if, in our endeavor to be justified in Christ, we too were found to be sinners, is Christ then a servant of sin? Certainly not! For if I rebuild what I tore down, I prove myself to be a transgressor. For through the law I died to the law, so that I might live to God. I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me. I do not nullify the grace of God, for if righteousness were through the law, then Christ died for no purpose."
"If the believer's justification is based upon the work of Christ and the obedience of the believer, then Christ came in vain. In other words, the work of Christ is insufficient to save and requires augmentation -the addition of the believer's obedience. If the false teachers are correct, then Christ did not secure salvation for anyone, but only the possibility or opportunity for salvation to those willing to complete their salvation with their own good works. This, however, is the farthest from the truth. This is why Paul calls the Galatians heresy a false gospel. Christ did not come to give people their possibility or the chance at salvation; he came to save his people from the wrath of God: actually, finally, completely, eternally, and immutably." (emphasis mine)I can only say, Amen and Amen! All glory be to God who saves!
