'Unless' in the Bible

For in what respect were you treated as inferior to the rest of the churches, except [for the fact] that I did not burden you [with my financial support]? Forgive me [for doing you] this injustice!

Test and evaluate yourselves to see whether you are in the faith and living your lives as [committed] believers. Examine yourselves [not me]! Or do you not recognize this about yourselves [by an ongoing experience] that Jesus Christ is in you—unless indeed you fail the test and are rejected as counterfeit?
