NET
5 Put yourselves to the test to see if you are in the faith; examine yourselves! Or do you not recognize regarding yourselves that Jesus Christ is in you—unless, indeed, you fail the test!
Darby
5 examine your own selves if ye be in the faith; prove your own selves: do ye not recognise yourselves, that Jesus Christ is in you, unless indeed ye be reprobates?
KJV
5 Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
