what we have seen and heard, we announce to you also, in order that you also may have fellowship with us, and indeed our fellowship [is] with the Father and with his Son Jesus Christ.

and he is the propitiation for our sins, and not for ours only, but also for [the sins of] the whole world.

The one who says [that he] resides in him ought also to walk just as that one walked.

Everyone who denies the Son does not have the Father [either]; the one who confesses the Son has the Father also.

[As for] you, what you have heard from the beginning must remain in you. If what you have heard from the beginning remains in you, you also will remain in the Son and in the Father.

Everyone who practices sin also practices lawlessness, and sin is lawlessness.

Dear friends, if God loved us in this way, we also ought to love one another.

By this love is perfected with us, so that we may have confidence in the day of judgment, because just as that one is, [so] also are we in this world.

And this [is] the commandment we have from him: that the one who loves God should love his brother also.

Everyone who believes that Jesus is the Christ has been fathered by God, and everyone who loves {the father} also loves the [child] fathered by him.
