if we say that we have communion with him, and walk in darkness, we lye, and do not act sincerely:

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

By this we can distinguish God's children and the Devil's children: no one who fails to act righteously is a child of God, nor he who does not love his brother man.

Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren.

My little children, do not let our love be in word and in tongue, but let it be in act and in good faith.

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

Here is what a complete love will do for us: It will give us boldness in [facing] the judgment day, because the way Jesus acts [regarding love] is the way we should act [while] in this world.

If we [are willing to] accept the testimony of people about matters, [surely we ought to accept that] the testimony of God is more reliable; because the testimony of God is that He has presented [confirming] testimony concerning [the identity and mission of] His Son.

And this is the confidence that we have in him: that if we ask ought, according to his will, he heareth us.
