Abraham’s Promise was Through the Righteousness of Faith

What then shall we say that Abraham our father has found according to the flesh? For if Abraham was justified by works, he has something to boast about, but not before God. For what does the Scripture say? “Abraham believed God, and it was accounted to him for righteousness.” Now to him who works, the wages are not counted as grace but as debt. But to him who does not work but believes on Him who justifies the ungodly, his faith is accounted for righteousness, just as David also describes the blessedness of the man to whom God imputes righteousness apart from works: “Blessed  are  those whose lawless deeds are forgiven, And whose sins are covered; Blessed is  the man to whom the Lord shall not impute sin.” 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. How then was it accounted? While he was circumcised, or uncircumcised? Not while circumcised, but while uncircumcised. 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, 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. 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. For if those who are of the law are heirs, faith is made void and the promise made of no effect, because the law brings about wrath; for where there is no law there  is no transgression. 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 (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; 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.” Romans 4:1‭-‬18 NKJV

Micah Takes a Levite as a Priest

​Now there was a man from the mountains of Ephraim, whose name was  Micah. And he said to his mother, “The eleven hundred shekels of silver that were taken from you, and on which you put a curse, even saying it in my ears—here is the silver with me; I took it.” And his mother said, “ May  you  be blessed by the Lord , my son!” So when he had returned the eleven hundred shekels of silver to his mother, his mother said, “I had wholly dedicated the silver from my hand to the Lord for my son, to make a carved image and a molded image; now therefore, I will return it to you.” Thus he returned the silver to his mother. Then his mother took two hundred shekels of silver and gave them to the silversmith, and he made it into a carved image and a molded image; and they were in the house of Micah. The man Micah had a shrine, and made an ephod and household idols; and he consecrated one of his sons, who became his priest. In those days there  was no king in Israel; everyone did what  was right in his own eyes. Now there was a young man from Bethlehem in Judah, of the family of Judah; he was a Levite, and was staying there. The man departed from the city of Bethlehem in Judah to stay wherever he could find a  place. Then he came to the mountains of Ephraim, to the house of Micah, as he journeyed. And Micah said to him, “Where do you come from?” So he said to him, “I am a Levite from Bethlehem in Judah, and I am on my way to find a  place to stay.” Micah said to him, “Dwell with me, and be a father and a priest to me, and I will give you ten shekels of silver per year, a suit of clothes, and your sustenance.” So the Levite went in. Then the Levite was content to dwell with the man; and the young man became like one of his sons to him. So Micah consecrated the Levite, and the young man became his priest, and lived in the house of Micah. Then Micah said, “Now I know that the Lord will be good to me, since I have a Levite as priest!” Judges 17:1‭-‬13 NKJV
