If we make it our habit to confess our sins, in his faithful righteousness he forgives us for those sins and cleanses us from all unrighteousness.

He Himself is the propitiation for our sins, and not only for ours, but also for those of the whole world.

They have gone out from our own number, but they did not really belong to us; for if they had, they would have stayed with us. It was to show that none of those who went out really belonged to us.

These things have I written to you concerning those who lead you astray:

Here is how the children of God and the children of the devil can be recognized: All those who do not continue to do what is right do not belong to God. Also, the person who does not continue to love his brother [or sister does not belong to God].

not as Cain was of the wicked one, and slew his brother; and on account of what slew he him? because his works were wicked, and those of his brother righteous.

By this we know [and have come to understand the depth and essence of His precious] love: that He [willingly] laid down His life for us [because He loved us]. And we ought to lay down our lives for the believers.

And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight.

Now those who keep his commandments abide in him, and he in them. And by this we know that he abides in us, by the Spirit whom he has given us.

Those men belong to the world; and therefore they speak as the world speaks, and the world listens to them.

We [who preach the true Gospel] represent God; the person who knows God listens to our message; the one who does not belong to God does not listen to us. This is how we can know [the difference between those speaking by] the Holy Spirit of truth and [those speaking by] the spirit of [Satan's] error.

Everyone who believes that Jesus is the Christ is a child of God, and everyone who loves the Father loves those who are his children.

Because those who testify are three:

I have written these things unto you, in order that you may know that you have eternal life; to those who believe on the name of the Son of God.

If any one see his brother sinning a sin not unto death, he shall ask, and he shall give him life, for those that do not sin unto death. There is a sin to death: I do not say of that that he should make a request.
