Romans 4:1 What shall we say then that Abraham our father, as pertaining to the flesh, hath found?
Romans 4:2 For if Abraham were justified by works, he hath [whereof] to glory; but not before God.
Romans 4:3 For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness.
Romans 4:4 Now to him that worketh is the reward not reckoned of grace, but of debt.
Romans 4:5 But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness.
Romans 4:6 Even as David also describeth the blessedness of the man, unto whom God imputeth righteousness without works,
Romans 4:7 [Saying], Blessed [are] they whose iniquities are forgiven, and whose sins are covered.
Romans 4:8 Blessed [is] the man to whom the Lord will not impute sin.
Works does nothing according to Paul, it was and is faith that God traded for righteousness in Abraham's case and in all of ours. Hebrews backs this up, further expanding on it and leaving no path of escape for dissemblers and judaizers in modern drag. Faith, not works.
Eph 2: 8,9 For by grace you have been saved through faith; and that not of yourselves, it is the gift of God; not as a result of works, so that no one may boast.
