but if we [really] walk in the Light [that is, live each and every day in conformity with the precepts of God], as He Himself is in the Light, we have [true, unbroken] fellowship with one another [He with us, and we with Him], and the blood of Jesus His Son cleanses us from all sin [by erasing the stain of sin, keeping us cleansed from sin in all its forms and manifestations].

And He [that same Jesus] is the propitiation for our sins [the atoning sacrifice that holds back the wrath of God that would otherwise be directed at us because of our sinful nature—our worldliness, our lifestyle]; and not for ours alone, but also for [the sins of all believers throughout] the whole world.

He that saith he abideth in him ought himself also so to walk, even as he walked.

This is the promise which He Himself promised us—eternal life.

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

You know that He appeared [in visible form as a man] in order to take away sins; and in Him there is [absolutely] no sin [for He has neither the sin nature nor has He committed sin or acts worthy of blame].

Every one hating his brother is a murderer: and you know that no murderer has eternal life abiding in himself.

Let us love with divine love, because he himself first loved us with divine love.

The fact that we love God Himself, and obey His commands, is a proof that we love God's children.

He it is whose Coming was attested by means of Water and Blood--Jesus Christ himself; not by Water only, but by Water and by Blood. And there is the Spirit also to bear testimony, and the Spirit is Truth itself.

He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son.

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

but he that is born of God keepeth himself, and the wicked one toucheth him not. We know, that we are of God, and the whole world lieth in the wicked one.
