'One' in the Bible

but if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus his Son cleanseth us from all sin.

I write unto you, fathers, because ye know him who is from the beginning. I write unto you, young men, because ye have overcome the evil one. I have written unto you, little children, because ye know the Father.

I have written unto you, fathers, because ye know him who is from the beginning. I have written unto you, young men, because ye are strong, and the word of God abideth in you, and ye have overcome the evil one.

And ye have an anointing from the Holy One, and ye know all the things.

And as for you, the anointing which ye received of him abideth in you, and ye need not that any one teach you; but as his anointing teacheth you; concerning all things, and is true, and is no lie, and even as it taught you, ye abide in him.

If ye know that he is righteous, ye know that every one also that doeth righteousness is begotten of him.

And every one that hath this hope'set on him purifieth himself, even as he is pure.

Every one that doeth sin doeth also lawlessness; and sin is lawlessness.

For this is the message which ye heard from the beginning, that we should love one another:

not as Cain was of the evil one, and slew his brother. And wherefore slew he him? Because his works were evil, and his brother's righteous.

And this is his commandment, that we should believe in the name of his Son Jesus Christ, and love one another, even as he gave us commandment.

Beloved, let us love one another: for love is of God; and every one that loveth is begotten of God, and knoweth God.

Beloved, if God so loved us, we also ought to love one another.

No man hath beheld God at any time: if we love one another, God abideth in us, and his love is perfected in us:

For there are three who bear witness, the Spirit, and the water, and the blood: and the three agree in one.

We know that whosoever is begotten of God sinneth not; but he that was begotten of God keepeth himself, and the evil one toucheth him not.

We know that we are of God, and the whole world lieth in the evil one.
