2 Corinthians 13:1-4

1This is the third time I am coming to you. Every charge must be established by the evidence of two or three witnesses. 2I warned those who sinned before and all the others, and I warn them now while absent, as I did when present on my second visit, that if I come again I will not spare them— 3since you seek proof that Christ is speaking in me. He is not weak in dealing with you, but is powerful among you. 4For he was crucified in weakness, but lives by the power of God. For we also are weak in him, but in dealing with you we will live with him by the power of God.
