Examine yourselves to see whether you are in the faith; test yourselves. Do you not realize that Jesus Christ is in you—unless you fail the test?
KJV
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?
ASV
Try your own selves, whether ye are in the faith; prove your own selves. Or know ye not as to your own selves, that Jesus Christ is in you? unless indeed ye be reprobate.
