'One' in the Bible

Only it came to their ears that he who at one time was cruel to us is now preaching the faith which before had been attacked by him;

Give me an answer to this one question, Did the Spirit come to you through the works of the law, or by the hearing of faith?

Brothers, as men would say, even a man's agreement, when it has been made certain, may not be put on one side, or have additions made to it.

Now to Abraham were the undertakings given, and to his seed. He says not, And to seeds, as of a great number; but as of one, he says, And to your seed, which is Christ.

Now a go-between is not a go-between of one; but God is one.

There is no Jew or Greek, servant or free, male or female: because you are all one in Jesus Christ.

Because it is in the Writings, that Abraham had two sons, one by the servant-woman, and one by the free woman.

Which things have a secret sense; because these women are the two agreements; one from the mountain of Sinai, giving birth to servants, which is Hagar.

Because you, brothers, were marked out to be free; only do not make use of your free condition to give the flesh its chance, but through love be servants one to another.

For all the law is made complete in one word, even in this, Have love for your neighbour as for yourself.

But if you are given to fighting with one another, take care that you are not the cause of destruction one to another.

For the flesh has desires against the Spirit, and the Spirit against the flesh; because these are opposite the one to the other; so that you may not do the things which you have a mind to do.

Let us not be full of self-glory, making one another angry, having envy of one another.

Brothers, if a man is taken in any wrongdoing, you who are of the Spirit will put such a one right in a spirit of love; keeping watch on yourself, for fear that you yourself may be tested.

Take on yourselves one another's troubles, and so keep the law of Christ.
