For what does the Scripture say?

Abraham believed God,
and it was credited to him for righteousness.

Is this blessing only for the circumcised, then? Or is it also for the uncircumcised? For we say, Faith was credited to Abraham for righteousness.

And he became the father of the circumcised, who are not only circumcised but who also follow in the footsteps of the faith our father Abraham had while he was still uncircumcised.

For the promise to Abraham or to his descendants that he would inherit the world was not through the law, but through the righteousness that comes by faith.

This is why the promise is by faith, so that it may be according to grace, to guarantee it to all the descendants—not only to those who are of the law but also to those who are of Abraham’s faith. He is the father of us all

Now it was credited to him was not written for Abraham alone,

Neither are they all children because they are Abraham’s descendants. On the contrary, your offspring will be traced through Isaac.

I ask, then, has God rejected His people? Absolutely not! For I too am an Israelite, a descendant of Abraham, from the tribe of Benjamin.

Are they Hebrews? So am I.
Are they Israelites? So am I.
Are they the seed of Abraham? So am I.

Just as Abraham believed God, and it was credited to him for righteousness,

then understand that those who have faith are Abraham’s sons.

Now the Scripture saw in advance that God would justify the Gentiles by faith and told the good news ahead of time to Abraham, saying, All the nations will be blessed through you.

So those who have faith are blessed with Abraham, who had faith.

The purpose was that the blessing of Abraham would come to the Gentiles by Christ Jesus, so that we could receive the promised Spirit through faith.

Now the promises were spoken to Abraham and to his seed. He does not say “and to seeds,” as though referring to many, but referring to one, and to your seed, who is Christ.

For if the inheritance is from the law, it is no longer from the promise; but God granted it to Abraham through the promise.

And if you belong to Christ, then you are Abraham’s seed, heirs according to the promise.

For it is written that Abraham had two sons, one by a slave and the other by a free woman.

For it is clear that He does not reach out to help angels, but to help Abraham’s offspring.

For when God made a promise to Abraham, since He had no one greater to swear by, He swore by Himself:

And so, after waiting patiently, Abraham obtained the promise.

For this Melchizedek—

King of Salem, priest of the Most High God,
who met Abraham and blessed him
as he returned from defeating the kings,

and Abraham gave him a tenth of everything;
first, his name means king of righteousness,
then also, king of Salem,
meaning king of peace;

Now consider how great this man was—even Abraham the patriarch gave a tenth of the plunder to him!

The sons of Levi who receive the priestly office have a command according to the law to collect a tenth from the people—that is, from their brothers—though they have also descended from Abraham.

But one without this lineage collected tenths from Abraham and blessed the one who had the promises.

And in a sense Levi himself, who receives tenths, has paid tenths through Abraham,

By faith Abraham, when he was called, obeyed and went out to a place he was going to receive as an inheritance. He went out, not knowing where he was going.

By faith Abraham, when he was tested, offered up Isaac. He received the promises and he was offering his unique son,

Wasn’t Abraham our father justified by works when he offered Isaac his son on the altar?

So the Scripture was fulfilled that says, Abraham believed God, and it was credited to him for righteousness, and he was called God’s friend.

just as Sarah obeyed Abraham, calling him lord. You have become her children when you do what is good and are not frightened by anything alarming.
