I'm not talking about the Jews under the law, I am talking about all, Jew and Gentile, who have sinned against God for all have sinned and need to reconcile themselves back to Gods grace as that comes by repentance or recognizing we are a sinner needing Gods grace we are saved through faith which is Christ Jesus. If a man says he has no sin that makes him a liar for all have sinned, Jew and Gentile.
Romans 3:23 For all have sinned, and come short of the glory of God; 24 Being justified freely by his grace through the redemption that is in Christ Jesus: 25 Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; 26 To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus. 27 Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith. 28 Therefore we conclude that a man is justified by faith without the deeds of the law. 29 Is he the God of the Jews only? is he not also of the Gentiles? Yes, of the Gentiles also: 30 Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith.
Ephesians 2:
8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: 9 Not of works, lest any man should boast. 10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them. 11 Wherefore remember, that ye being in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands; 12 That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world: 13 But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ.
1 John 1:8 If we say that we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. 10 If we say that we have not sinned, we make him a liar, and his word is not in us.
