'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 written to you because you do not know the truth, but because you do know it, and because no lie [nothing false, no deception] is of the truth.

whenever our heart convicts us [in guilt]; for God is greater than our heart and He knows all things [nothing is hidden from Him because we are in His hands].
