2 Corinthians 13:1-3; 2 Corinthians 13:10
This is the third time I am coming to you. Any charge must be sustained by the evidence of two or three witnesses.
I 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--
since you desire proof that Christ is speaking in me. He is not weak in dealing with you, but is powerful in you.
I write this while I am away from you, in order that when I come I may not have to be severe in my use of the authority which the Lord has given me for building up and not for tearing down.
