'Anyone' 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],

Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him,

And [as for] you, the anointing which you received from him remains in you, and you do not have need that anyone teach you. But as his anointing teaches you about all [things], and is true and is not a lie, and just as it has taught you, you reside in him.

If anyone says, "I love God," and hates his brother, he is a liar, for the one who does not love his brother whom he has seen is not able to love God whom he has not seen.

If anyone should see his brother sinning a sin not [leading] to death, he should ask, and he will grant life to him, to those who sin not [leading] to death. ([There] is a sin [leading] to death; I do not say that he should ask about that.
