'One' in the Bible

But if we are walking in the light, as he is in the light, we are all united with one another, and the blood of Jesus his Son makes us clean from all sin.

My little children, I am writing these things to you so that you may be without sin. And if any man is a sinner, we have a friend and helper with the Father, Jesus Christ, the upright one:

I am writing to you, fathers, because you have knowledge of him who was from the first. I am writing to you, young men, because you have overcome the Evil One. I have sent a letter to you, children, because you have knowledge of the Father.

I have sent a letter to you, fathers, because you have knowledge of him who was from the first. I have sent a letter to you, young men, because you are strong, and the word of God is in you, and because you have overcome the Evil One.

And you have the Spirit from the Holy One and you all have knowledge.

The sinner is a child of the Evil One; for the Evil One has been a sinner from the first. And the Son of God was seen on earth so that he might put an end to the works of the Evil One.

In this way it is clear who are the children of God and who are the children of the Evil One; anyone who does not do righteousness or who has no love for his brother, is not a child of God.

Because this is the word which was given to you from the first, that we are to have love for one another;

Not being of the Evil One like Cain, who put his brother to death. And why did he put him to death? Because his works were evil and his brother's works were good.

And this is his law, that we have faith in the name of his Son Jesus Christ, and love for one another, even as he said to us.

My loved ones, let us have love for one another: because love is of God, and everyone who has love is a child of God and has knowledge of God.

My loved ones, if God had such love for us, it is right for us to have love for one another.

No man has ever seen God: if we have love for one another, God is in us and his love is made complete in us:

We are certain that one who is a child of God will do no sin, but the Son of God keeps him so that he is not touched by the Evil One.

We are certain that we are of God, but all the world is in the power of the Evil One.
