The Grace of Justification by Faith Alone

Romans 3 (KJV):

⁹What then? are we better than they? No, in no wise: for we have before proved both Jews and Gentiles, that they are all under sin; ¹⁰As it is written, There is none righteous, no, not one: ¹¹There is none that understandeth, there is none that seeketh after God. ¹²They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one. ¹³Their throat is an open sepulchre; with their tongues they have used deceit; the poison of asps is under their lips:  ¹⁴Whose mouth is full of cursing and bitterness: ¹⁵Their feet are swift to shed blood: ¹⁶Destruction and misery are in their ways: ¹⁷And the way of peace have they not known: ¹⁸There is no fear of God before their eyes. ¹⁹Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God. ²⁰Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin. ²¹But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets; ²²Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference: ²³For all have sinned, and come short of the glory of God; ²⁴Being justified freely by his grace through the redemption that is in Christ Jesus: ²⁵Whom 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; ²⁶To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus. ²⁷Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith. ²⁸Therefore we conclude that a man is justified by faith without the deeds of the law. ²⁹Is he the God of the Jews only? is he not also of the Gentiles? Yes, of the Gentiles also: ³⁰Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith. ³¹Do we then make void the law through faith? God forbid: yea, we establish the law.

Romans 4 (KJV):

¹What shall we say then that Abraham our father, as pertaining to the flesh, hath found? ²For if Abraham were justified by works, he hath whereof to glory; but not before God.  ³For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness. ⁴Now to him that worketh is the reward not reckoned of grace, but of debt. ⁵But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness. ⁶Even as David also describeth the blessedness of the man, unto whom God imputeth righteousness without works, ⁷Saying, Blessed are they whose iniquities are forgiven, and whose sins are covered. ⁸Blessed is the man to whom the Lord will not impute sin. ⁹Cometh this blessedness then upon the circumcision only, or upon the uncircumcision also? for we say that faith was reckoned to Abraham for righteousness.

Ephesians 2:8-10 (KJV):

 ⁸For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:  ⁹Not of works, lest any man should boast. ¹⁰For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.

Galatians 2 (KJV): 

¹⁶Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified. ¹⁷But if, while we seek to be justified by Christ, we ourselves also are found sinners, is therefore Christ the minister of sin? God forbid. ¹⁸For if I build again the things which I destroyed, I make myself a transgressor. ¹⁹For I through the law am dead to the law, that I might live unto God. ²⁰I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. ²¹I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.
