II Corinthians 13:3-6

since you seek a proof of Christ speaking in me, who is not weak toward you, but mighty in you. For though He was crucified in weakness, yet He lives by the power of God. For we also are weak in Him, but we shall live with Him by the power of God toward you. Examine yourselves as to whether you are in the faith. Test yourselves. Do you not know yourselves, that Jesus Christ is in you?—unless indeed you are disqualified. But I trust that you will know that we are not disqualified.
