And this is the promise which we have heard from him, and declare unto you, that God is light, and that darkness in him there is none.

But whosoever keepeth his word, verily in him is the love of God perfected: by this we know that we are in him.

Who is the liar, but he that denieth that Jesus is the Messiah? This man is the antichrist, who denieth the Father and the Son.

And this is the promise which he hath promised to us, even life eternal.

And every one who hath this hope in him purifieth himself, even as he is pure.

he that practises sin is of the devil; for from the beginning the devil sinneth. For this purpose the Son of God was manifested, that he might destroy the works of the devil.

By this the children of God are manifestly seen, and the children of the devil. Every one that doth not practise righteousness, is not of God, and he that loveth not his brother.

For this is the commandment which ye have heard from the beginning, that we should love one another.

By this we have known the love [of Christ], because for us he laid down his own life: and we ought to lay down our lives for the brethren.

and hereby we know that we are of the truth, and in his presence have this persuasion in our hearts.

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

And he that keepeth his commandments abideth in him, and he in him; and by this we know that he abideth in us, from the Spirit which he hath given us.

By this ye know the Spirit of God: every spirit who confesseth that Jesus the Messiah is come in the flesh, is from God.

And every spirit who confesseth not that Jesus the Messiah is come into the world, is not from God: and this is that spirit of antichrist which ye have heard that it is coming, and now is already in the world.

We are of God: he that knoweth God heareth us; he that is not of God heareth us not. By this we know the spirit of truth and the spirit of delusion.

By this was the love of God manifested to us, that God sent his only begotten Son into the world, that we might have life by him.

By this we know that we abide in him, and he in us, because he hath given us of his own Spirit.

By this is his love towards us perfected, that we might have confidence at the day of judgment; because as he is, so are we in this world.

Fear is not in this love; but the perfect love casteth out fear: for fear hath anguish. He that is afraid is not made perfect in love.

So this commandment have we from him, that he who loveth God love also his brother.

For this is the love of God, that we should keep his commandments: and his commandments are not burdensome.

Because every one that is born of God overcometh the world: and this is the victory which overcometh the world, our faith.

This is he who came by water and blood, Jesus the Messiah; not by the water only, but by the water and the blood: and the Spirit is the witnessing person, because the Spirit is the truth.

If we receive the testimony of man, the testimony of God is stronger: for this is the testimony of God which he testified concerning his Son.

And this is the testimony, that God hath given life eternal to us; and this life is in his Son.

He that hath the Son, hath this life; and he that hath not the Son of God, hath not this life.

And this is the confidence that we have towards him, that whatsoever we ask according to his will, he heareth us.
