Abraham's faith was imputed to him for righteousness,
Romans 4:1 What, then, shall we say Abraham our father, to have found, according to flesh? Romans 4:2 for if Abraham by works was declared righteous, he hath to boastbut not before God; Romans 4:3 for what doth the writing say? 'And Abraham did believe God, and it was reckoned to himto righteousness;' Romans 4:4 and to him who is working, the reward is not reckoned of grace, but of debt; Romans 4:5 and to him who is not working, and is believing upon Him who is declaring righteous the impious, his faith is reckonedto righteousness: Romans 4:6 even as David also doth speak of the happiness of the man to whom God doth reckon righteousness apart from works: Romans 4:7 'Happy they whose lawless acts were forgiven, and whose sins were covered; Romans 4:8 happy the man to whom the Lord may not reckon sin.' Romans 4:9 [Is] this happiness, then, upon the circumcision, or also upon the uncircumcisionfor we say that the faith was reckoned to Abrahamto righteousness?
before he was circumcised.
Romans 4:10 how then was it reckoned? he being in circumcision, or in uncircumcision? not in circumcision, but in uncircumcision; Romans 4:11 and a sign he did receive of circumcision, a seal of the righteousness of the faith in the uncircumcision, for his being father of all those believing through uncircumcision, for the righteousness also being reckoned to them, Romans 4:12 and father of circumcision to those not of circumcision only, but who also walk in the steps of the faith, that [is] in the uncircumcision of our father Abraham.
By faith only he and his seed received the promise.
Romans 4:13 For not through law [is] the promise to Abraham, or to his seed, of his being heir of the world, but through the righteousness of faith; Romans 4:14 for if they who are of law [are] heirs, the faith hath been made void, and the promise hath been made useless; Romans 4:15 for the law doth work wrath; for where law is not, neither [is] transgression.
Abraham is the father of all that believe.
Romans 4:16 Because of this [it is] of faith, that [it may be] according to grace, for the promise being sure to all the seed, not to that which [is] of the law only, but also to that which [is] of the faith of Abraham, Romans 4:17 who is father of us all (according as it hath been written'A father of many nations I have set thee,') before Him whom he did believeGod, who is quickening the dead, and is calling the things that be not as being. Romans 4:18 Who, against hope in hope did believe, for his becoming father of many nations according to that spoken: 'So shall thy seed be;' Romans 4:19 and not having been weak in the faith, he did not consider his own body, already become dead, (being about a hundred years old,) and the deadness of Sarah's womb, Romans 4:20 and at the promise of God did not stagger in unbelief, but was strengthened in faith, having given glory to God, Romans 4:21 and having been fully persuaded that what He hath promised He is able also to do: Romans 4:22 wherefore also it was reckoned to him to righteousness. Romans 4:23 And it was not written on his account alone, that it was reckoned to him,
Our faith also shall be imputed to us for righteousness.
Romans 4:24 but also on ours, to whom it is about to be reckonedto us believing on Him who did raise up Jesus our Lord out of the dead, Romans 4:25 who was delivered up because of our offences, and was raised up because of our being declared righteous.
