2 Corinthians 13:1-4

This will be my third visit to you. “Every matter must be established by the testimony of two or three witnesses.” I already gave you a warning when I was with you the second time. I now repeat it while absent: On my return I will not spare those who sinned earlier or any of the others, since you are demanding proof that Christ is speaking through me. He is not weak in dealing with you, but is powerful among you. For to be sure, he was crucified in weakness, yet he lives by God’s power. Likewise, we are weak in him, yet by God’s power we will live with him in our dealing with you.
