'Little 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.

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.

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

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.

Little children, guard yourselves from idols.
