'Unqualified' in the Bible

Test yourselves [to see] if you are in the faith. Examine yourselves! Or do you not recognize regarding yourselves that Jesus Christ [is] in you, unless you are unqualified?

And I hope that you will recognize that we are not unqualified!

Now we pray to God that you not do wrong in any way, not that we are seen as approved, but that you do what is good, even [though] we are [seen] as though unqualified.

I remember your sincere and unqualified faith [the surrendering of your entire self to God in Christ with confident trust in His power, wisdom and goodness, a faith] which first lived in [the heart of] your grandmother Lois and your mother Eunice, and I am confident that it is in you as well.

to slander or abuse no one, to be kind and conciliatory and gentle, showing unqualified consideration and courtesy toward everyone.

let us approach [God] with a true and sincere heart in unqualified assurance of faith, having had our hearts sprinkled clean from an evil conscience and our bodies washed with pure water.
