'One' in the Bible

I am astonished that you are so quickly deserting the one who called you by the grace of the Messiah and, instead, are following a different gospel,

not that another one really exists. To be sure, there are certain people who are troubling you and want to distort the gospel about the Messiah.

For the one who worked through Peter by making him an apostle to the circumcised also worked through me by sending me to the gentiles.

I want to learn only one thing from you: Did you receive the Spirit by doing the actions of the Law or by believing what you heard?

Therefore, those who believe are blessed together with Abraham, the one who believed.

Now it is obvious that no one is justified in the sight of God by the Law, because "The righteous will live by faith."

Brothers, let me use an example from everyday life. Once an agreement has been ratified, no one can cancel it or add conditions to it.

Now the promises were spoken to Abraham and to his descendant. It doesn't say "descendants," referring to many, but "your descendant," referring to one person, who is the Messiah.

Now a mediator involves more than one party, but God is one.

Because all of you are one in the Messiah Jesus, a person is no longer a Jew or a Greek, a slave or a free person, a male or a female.

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

This is being said as an allegory, for these women represent two covenants. The one woman, Hagar, is from Mount Sinai, and her children are born into slavery.

Such influence does not come from the one who calls you.

I am confident in the Lord that you will take no other view of this. However, the one who is troubling you will suffer God's judgment, whoever he is.

For you, brothers, were called to freedom. Only do not turn your freedom into an opportunity to gratify your flesh, but through love make it your habit to serve one another.

But if you bite and devour one another, be careful that you are not destroyed by each other.

Let's stop being arrogant, provoking one another and envying one another.

Let no one make any more trouble for me, because I carry the scars of Jesus on my own body.
