'Nothing' in the Bible

Or is it nothing to you that God had pity on you, waiting and putting up with you for so long, not seeing that in his pity God's desire is to give you a change of heart?

For I am conscious that in me, that is, in my flesh, there is nothing good: I have the mind but not the power to do what is right.

For he is the servant of God to you for good. But if you do evil, have fear; for the sword is not in his hand for nothing: he is God's servant, making God's punishment come on the evil-doer.

Be in debt for nothing, but to have love for one another: for he who has love for his neighbour has kept all the law.

I am conscious of this, and am certain in the Lord Jesus, that nothing is unclean in itself; but for the man in whose opinion it is unclean, for him it is unclean.

Do not let the work of God come to nothing on account of food. All things are certainly clean; but it is evil for that man who by taking food makes it hard for another.
