'Nothing' in the Bible

This is the word which came to us from him and which we give to you, that God is light and in him there is nothing dark.

If we say that we have no sin, we are false to ourselves and there is nothing true in us.

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

I have not sent you this letter because you have no knowledge of what is true, but because you have knowledge, and because that which is false has nothing in common with that which is true.
