One who says, "I know him," and doesn't keep his commandments, is a liar, and the truth isn't in him.

But the one who hates his brother is in the darkness, walks in the darkness, and doesn’t know where he’s going, because the darkness has blinded his eyes.

Whoever denies the Son, the same doesn't have the Father. He who confesses the Son has the Father also.

Behold, how great a love the Father has bestowed on us, that we should be called children of God! For this cause the world doesn't know us, because it didn't know him.

Whoever remains in him doesn't sin. Whoever sins hasn't seen him, neither knows him.

Whoever is born of God doesn't commit sin, because his seed remains in him; and he can't sin, because he is born of God.

In this the children of God are revealed, and the children of the devil. Whoever doesn't do righteousness is not of God, neither is he who doesn't love his brother.

We know that we have passed out of death into life, because we love the brothers. He who doesn't love his brother remains in death.

and every spirit who doesn't confess that Jesus Christ has come in the flesh is not of God, and this is the spirit of the Antichrist, of whom you have heard that it comes. Now it is in the world already.

We are of God. He who knows God listens to us. He who is not of God doesn't listen to us. By this we know the spirit of truth, and the spirit of error.

He who doesn't love doesn't know God, for God is love.

If a man says, "I love God," and hates his brother, he is a liar; for he who doesn't love his brother whom he has seen, how can he love God whom he has not seen?

He who believes in the Son of God has the testimony in himself. He who doesn't believe God has made him a liar, because he has not believed in the testimony that God has given concerning his Son.

The one who has the Son has life. The one who doesn’t have the Son of God does not have life.

If anyone sees his brother committing a sin that does not bring death, he should ask, and God will give life to him—to those who commit sin that doesn’t bring death. There is sin that brings death. I am not saying he should pray about that.

We know that whoever is born of God doesn't sin, but he who was born of God keeps himself, and the evil one doesn't touch him.
