2 Corinthians 13:5 in the King James Version
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?
Context
4 For he was crucified through weakness, yet he lives through the power of God. For we also are weak in him, but we will live with him through the power of God toward you.
5 Examine your own selves, whether you are in the faith. Test your own selves. Or don’t you know about your own selves, that Jesus Christ is in you?—unless indeed you are disqualified.
6 But I hope that you will know that we aren’t disqualified.
