'Unqualified' in the Bible

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.
