'One' in the Bible

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

But even if we (or an angel from heaven) should preach a gospel contrary to the one we preached to you, let him be condemned to hell!

As we have said before, and now I say again, if any one is preaching to you a gospel contrary to what you received, let him be condemned to hell!

But when the one who set me apart from birth and called me by his grace was pleased

They were only hearing, "The one who once persecuted us is now proclaiming the good news of the faith he once tried to destroy."

yet we know that no one is justified by the works of the law but by the faithfulness of Jesus Christ. And we have come to believe in Christ Jesus, so that we may be justified by the faithfulness of Christ and not by the works of the law, because by the works of the law no one will be justified.

But if while seeking to be justified in Christ we ourselves have also been found to be sinners, is Christ then one who encourages sin? Absolutely not!

But if I build up again those things I once destroyed, I demonstrate that I am one who breaks God's law.

Now it is clear no one is justified before God by the law, because the righteous one will live by faith.

But the law is not based on faith, but the one who does the works of the law will live by them.

Brothers and sisters, I offer an example from everyday life: When a covenant has been ratified, even though it is only a human contract, no one can set it aside or add anything to it.

Now the promises were spoken to Abraham and to his descendant. Scripture does not say, "and to the descendants," referring to many, but "and to your descendant," referring to one, who is Christ.

Now an intermediary is not for one party alone, but God is one.

There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female -- for all of you are one in Christ Jesus.

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

But one, the son by the slave woman, was born by natural descent, while the other, the son by the free woman, was born through the promise.

These things may be treated as an allegory, for these women represent two covenants. One is from Mount Sinai bearing children for slavery; this is Hagar.

But just as at that time the one born by natural descent persecuted the one born according to the Spirit, so it is now.

This persuasion does not come from the one who calls you!

I am confident in the Lord that you will accept no other view. But the one who is confusing you will pay the penalty, whoever he may be.

For you were called to freedom, brothers and sisters; only do not use your freedom as an opportunity to indulge your flesh, but through love serve one another.

However, if you continually bite and devour one another, beware that you are not consumed by one another.

Let us not become conceited, provoking one another, being jealous of one another.

Carry one another's burdens, and in this way you will fulfill the law of Christ.

Let each one examine his own work. Then he can take pride in himself and not compare himself with someone else.

For each one will carry his own load.

Now the one who receives instruction in the word must share all good things with the one who teaches it.

because the person who sows to his own flesh will reap corruption from the flesh, but the one who sows to the Spirit will reap eternal life from the Spirit.

From now on let no one cause me trouble, for I bear the marks of Jesus on my body.
