2 Corinthians 13:1-4

1This is the third time I am coming to you. “Every matter must be established by the testimony of two or three witnesses.”1

2I already warned you the second time I was with you. So now in my absence I warn those who sinned earlier and everyone else: If I return, I will not spare anyone, 3since you are demanding proof that Christ is speaking through me. He is not weak in dealing with you but is powerful among you. 4For He was indeed crucified in weakness, yet He lives by God’s power. For we are also weak in Him, yet by God’s power we will live with Him concerning you.
