'Children' in the Bible

My little children, I am writing these [things] to you in order that you may not sin. And if anyone sins, we have an advocate with the Father, Jesus Christ the righteous [one],

I am writing to you, little children, because your sins have been forgiven you on account of his name.

I have written to you, children, because you have known the Father. I have written to you, fathers, because you have known the [One who is] from the beginning. I have written to you, young men, because you are strong, and the word of God resides in you, and you have conquered the evil one.

Children, it is the last hour, and just as you have heard that antichrist is coming, even now many antichrists have arisen, by which we know that it is the last hour.

And now, little children, remain in him, so that whenever he is revealed we may have confidence and not be put to shame before him at his coming.

See what sort of love the Father has given to us: that we should be called children of God, and we are! Because of this the world does not know us: because it did not know him.

Dear friends, now we are children of God, and what we will be has not yet been revealed. We know that whenever he is revealed we will be like him, because we will see him just as he is.

Little children, let no one deceive you: the one who practices righteousness is righteous, just as that one is righteous.

By this the children of God and the children of the devil are evident: everyone who does not practice righteousness is not of God, namely, the one who does not love his brother.

Little children, let us not love with word or with tongue, but in deed and truth.

You are from God, little children, and have conquered them, because the one [who is] in you is greater than the one [who is] in the world.

By this we know that we love the children of God: whenever we love God and keep his commandments.

Little children, guard yourselves from idols.
