'Says' in the Bible

The man who says, I have knowledge of him, and does not keep his laws, is false, and there is nothing true in him:

He who says that he is living in him, will do as he did.

He who says that he is in the light, and has hate in his heart for his brother, is still in the dark.

Who is false but he who says that Jesus is not the Christ? He is the Antichrist who has no belief in the Father or the Son.

When our heart says that we have done wrong; because God is greater than our heart, and has knowledge of all things.

By this you may have knowledge of the Spirit of God: every spirit which says that Jesus Christ has come in the flesh is of God:

Everyone who says openly that Jesus is the Son of God, has God in him and is in God.

If a man says, I have love for God, and has hate for his brother, his words are false: for how is the man who has no love for his brother whom he has seen, able to have love for God whom he has not seen?
