That which we have seen and heard declare we unto you, that ye may have fellowship with us, and that our fellowship may be with the father, and his son Jesus Christ.

but and if we walk in light even as he is in light, then have we fellowship together, and the blood of Jesus Christ his son cleanseth us from all sin.

Who is a liar, but he that denieth that Jesus is Christ? The same is the antichrist that denieth the father and the son.

Whosoever denieth the son, the same hath not the father.

Let therefore abide in you that same which ye heard at the beginning. If that which ye heard at the beginning shall remain in you, then ye also shall continue in the son, and in the father.

Behold what love the father hath showed on us, that we should be called the sons of God. For this cause the world knoweth you not; because it knoweth not him.

Dearly beloved, now are we the sons of God, and yet it doth not appear what we shall be. But we know that when it shall appear, we shall be like him. For we shall see him as he is.

He that committeth sin is of the devil: for the devil sinneth since the beginning. But for this cause appeared the son of God, even to destroy the works of the devil.

And hereby are the sons of God known, and also the sons of the devil. All that work not righteousness, are not of God, nor he that loveth not his brother.

And this is his commandment, that we believe on the name of his son Jesus Christ, and love one another, as he gave commandment.

Herein appeared the love of God to us ward, because that God sent his only begotten son into the world, that we should live through him.

Herein is love, not that we loved God, but that he loved us, and sent his son to make a satisfaction for our sins.

And we have seen and do testify that the father hath sent his son, which is the saviour of the world.

Whosoever confesseth that Jesus is the son of God, in him dwelleth God, and he in God.

In this we know that we love the sons of God, when we love God, and keep his commandments.

Who is it that overcometh the world: but he which believeth that Jesus is the son of God?

If we receive the witness of men, the witness of God is greater. For this is the witness of God, that God hath born of his son.

He that believeth in the son of God hath the witness in himself. He that believeth not God, maketh him a liar, because he doth not believe the witness that God hath testified of his son.

And this is the witness: how that God hath given unto us eternal life, and this life is in his son.

He that hath the son, hath life: and he that hath not the son of God, hath not life.

These things have I written unto you that believe in the name of the son of God, that ye may know how that ye have everlasting life, and that ye may believe in the name of the son of God.

We know that the son of God is come, and hath given us understanding, to know him that is true: and we be in the truth through his son Jesus Christ. He is very God, and eternal life.
