'One' in the Bible

I am astonished that you are turning away so quickly from the one who called you by the grace of Christ to a different gospel,

But when the one who set me apart from my mother's womb and called [me] by his grace was pleased

and they were only hearing, "The one formerly persecuting us is now proclaiming the faith that formerly he was attempting to destroy,"

(for the one who was at work through Peter for [his] apostleship to the circumcision was at work also through me for the Gentiles),

Therefore does the one who gives you the Spirit and who works miracles among you [do so] by the works of the law, or by the hearing of faith?

Now [it is] clear that no one is justified in the sight of God by the law, because "the one who is righteous will live by faith."

But the law is not from faith, but "the one who does these [things] will live by them."

Brothers, I am speaking according to a human perspective. Nevertheless, [when] the covenant of a man has been ratified, no one declares [it] invalid or adds additional provisions [to it].

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

Now the mediator is not for one, but God is one.

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

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

But the one by the female slave was born according to human descent, and the one by the free woman through the promise,

which [things] are spoken allegorically, for these [women] are two covenants, one from Mount Sinai, bearing [children] for slavery, who is Hagar.

For it is written, "Rejoice, O barren woman, who does not give birth to [children]; burst out and shout, [you] who do not have birth pains, because many [are] the children of the desolate [woman], even more than [those of] the one who has a husband."

This persuasion [is] not from the one who calls you!

I have confidence in you in the Lord that you will think nothing different, but the one who is confusing you {will pay the penalty}, whoever he may be.

For you were called to freedom, brothers. Only do not let your freedom [become] an opportunity for the flesh, but through love serve one another.

For the whole law is fulfilled in one statement, namely, "You shall love your neighbor as yourself."

But if you bite and devour one another, watch out [that] you are not consumed by one another.

For the flesh desires against the Spirit, and the Spirit against the flesh, for these are in opposition to one another, so that whatever you want, you may not do these [things].

We must not become conceited, provoking one another, envying one another.

Carry the burdens of one another, and so fulfill the law of Christ.

But let each one examine his own work, and then he will have a reason for boasting in himself alone, and not in someone else.

For each one will carry his own burden.

Now the one who is taught the word must share in all good [things] with the one who teaches.

because the one 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.

Finally, let no one cause me trouble, for I carry on my body the marks of Jesus.
