4 What then shall we say that Abraham our father has found according to the flesh? 2 For if Abraham was justified by works, he has something to boast about, but not before God. 3 For what does the Scripture say? “Abraham believed God, and it was accounted to him for righteousness.” 4 Now to him who works, the wages are not counted as grace but as debt.
5 But to him who does not work but believes on Him who justifies the ungodly, his faith is accounted for righteousness, 6 just as David also describes the blessedness of the man to whom God imputes righteousness apart from works:
7 “Blessed are those whose lawless deeds are forgiven,
And whose sins are covered;
8 Blessed is the man to whom the Lord shall not impute sin.”
9 Does this blessedness then come upon the circumcised only, or upon the uncircumcised also? For we say that faith was accounted to Abraham for righteousness. 10 How then was it accounted? While he was circumcised, or uncircumcised? Not while circumcised, but while uncircumcised. 11 And he received the sign of circumcision, a seal of the righteousness of the faith which he had while still uncircumcised, that he might be the father of all those who believe, though they are uncircumcised, that righteousness might be imputed to them also, 12 and the father of circumcision to those who not only are of the circumcision, but who also walk in the steps of the faith which our father Abraham had while still uncircumcised.
13 For the promise that he would be the heir of the world was not to Abraham or to his seed through the law, but through the righteousness of faith. 14 For if those who are of the law are heirs, faith is made void and the promise made of no effect, 15 because the law brings about wrath; for where there is no law there is no transgression.
16 Therefore it is of faith that it might be according to grace, so that the promise might be sure to all the seed, not only to those who are of the law, but also to those who are of the faith of Abraham, who is the father of us all 17 (as it is written, “I have made you a father of many nations”) in the presence of Him whom he believed—God, who gives life to the dead and calls those things which do not exist as though they did; 18 who, contrary to hope, in hope believed, so that he became the father of many nations, according to what was spoken, “So shall your descendants be.” 19 And not being weak in faith, he did not consider his own body, already dead (since he was about a hundred years old), and the deadness of Sarah’s womb. 20 He did not waver at the promise of God through unbelief, but was strengthened in faith, giving glory to God, 21 and being fully convinced that what He had promised He was also able to perform. 22 And therefore “it was accounted to him for righteousness.”
23 Now it was not written for his sake alone that it was imputed to him, 24 but also for us. It shall be imputed to us who believe in Him who raised up Jesus our Lord from the dead, 25 who was delivered up because of our offenses, and was raised because of our justification. (Romans 4)
25 As He says also in Hosea:
“I will call them My people, who were not My people,
And her beloved, who was not beloved.”
26 “And it shall come to pass in the place where it was said to them,
‘You are not My people,’
There they shall be called sons of the living God.”
10 For it was fitting for Him, for whom are all things and by whom are all things, in bringing many sons to glory, to make the captain of their salvation perfect through sufferings. 11 For both He who sanctifies and those who are being sanctified are all of one, for which reason He is not ashamed to call them brethren, 12 saying:
“I will declare Your name to My brethren;
In the midst of the assembly I will sing praise to You.”
13 And again:
“I will put My trust in Him.”
“Here am I and the children whom God has given Me.”
14 Inasmuch then as the children have partaken of flesh and blood, He Himself likewise shared in the same, that through death He might destroy him who had the power of death, that is, the devil, 15 and release those who through fear of death were all their lifetime subject to bondage. 16 For indeed He does not give aid to angels, but He does give aid to the seed of Abraham. 17 Therefore, in all things He had to be made like His brethren, that He might be a merciful and faithful High Priest in things pertaining to God, to make propitiation for the sins of the people. 18 For in that He Himself has suffered, being tempted, He is able to aid those who are tempted. (Heb. 2:10-18)
So in the end, whose son are we? Are we Abraham’s son or God’s? Aren’t we simply sons of the Promise of Salvation in Christ through Faith in Him? Not by our works but what He has done. We are simply the fortunate lowlife sinners the Lord has had mercy upon.
