And these we write to you, that your joy might be filled up.

If we say that we have fellowship with him, and walk in darkness, we lie, and obey not the truth.

And by this we may know that we know Him--if we obey His commands.

Whoever says, “I have come to know Him,” but does not habitually keep [focused on His precepts and obey] His commandments (teachings), is a liar, and the truth [of the divine word] is not in him.

and the truth is not in him; bit if any man obey his word, in him truly is the love of God made perfect. By this we come to know that we are in him.

For all that makes up the world, namely, the improper desires of the physical body, the improper desires for what is seen, and the [boastful] pride over life's possessions; these are not from the Father, but from the [godless] world.

And ye know that that man was made known so that he might take up our sins. And in him is no sin.

he who is doing the sin, of the devil he is, because from the beginning the devil doth sin; for this was the Son of God manifested, that he may break up the works of the devil;

But whoso hath this world's good, and seeth his brother have need, and shutteth up his bowels of compassion from him, how dwelleth the love of God in him?

and we receive from Him whatever we ask because we [carefully and consistently] keep His commandments and do the things that are pleasing in His sight [habitually seeking to follow His plan for us].

The one who habitually keeps His commandments [obeying His word and following His precepts, abides and] remains in Him, and He in him. By this we know and have the proof that He [really] abides in us, by the Spirit whom He has given us [as a gift].

By this we know [without any doubt] that we love the children of God: [expressing that love] when we love God and obey His commandments.
