'Unworthy' in the Bible

Thus you also, when you have done all the {things you were ordered to do}, say, 'We are unworthy slaves; we have done what we were obligated to do.'"

Or do you not know that the saints will judge the world? And if by you the world is judged, are you unworthy of the most insignificant courts?

So then, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of the body and the blood of the Lord.
