'Person' in the Bible

The one who says "I have come to know God" and yet does not keep his commandments is a liar, and the truth is not in such a person.

But whoever obeys his word, truly in this person the love of God has been perfected. By this we know that we are in him.

And the world is passing away with all its desires, but the person who does the will of God remains forever.

Who is the liar but the person who denies that Jesus is the Christ? This one is the antichrist: the person who denies the Father and the Son.

Everyone who denies the Son does not have the Father either. The person who confesses the Son has the Father also.

But whoever has the world's possessions and sees his fellow Christian in need and shuts off his compassion against him, how can the love of God reside in such a person?

And the person who keeps his commandments resides in God, and God in him. Now by this we know that God resides in us: by the Spirit he has given us.

We are from God; the person who knows God listens to us, but whoever is not from God does not listen to us. By this we know the Spirit of truth and the spirit of deceit.

The person who does not love does not know God, because God is love.

Now who is the person who has conquered the world except the one who believes that Jesus is the Son of God?

If anyone sees his fellow Christian committing a sin not resulting in death, he should ask, and God will grant life to the person who commits a sin not resulting in death. There is a sin resulting in death. I do not say that he should ask about that.
