For I fear that perhaps when I come I may find you not as I wish, and that you may find me not as you wish—that perhaps there may be quarreling, jealousy, anger, hostility, slander, gossip, conceit, and disorder. I fear that when I come again my God may humble me before you, and I may have to mourn over many of those who sinned earlier and have not repented of the impurity, sexual immorality, and sensuality that they have practiced.
13:1 This is the third time I am coming to you. Every charge must be established 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 seek proof that Christ is speaking in me. He is not weak in dealing with you, but is powerful among you. For 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.
Examine yourselves, to see whether you are in the faith. Test yourselves. Or do you not realize this about yourselves, that Jesus Christ is in you?—unless indeed you fail to meet the test! I hope you will find out that we have not failed the test. But we pray to God that you may not do wrong—not that we may appear to have met the test, but that you may do what is right, though we may seem to have failed. For we cannot do anything against the truth, but only for the truth. For we are glad when we are weak and you are strong. Your restoration is what we pray for. For this reason I write these things while I am away from you, that when I come I may not have to be severe in my use of the authority that the Lord has given me for building up and not for tearing down.
Deuteronomy 19:15 (ESV) > A single witness shall not suffice against a person for any crime or for any wrong in connection with any offense that he has committed. Only on the evidence of two witnesses or of three witnesses shall a charge be established.
Numbers 35:30 (ESV) > If anyone kills a person, the murderer shall be put to death on the evidence of witnesses. But no person shall be put to death on the testimony of one witness.
1 Corinthians 5:3-5 (ESV) > For though absent in body, I am present in spirit; and as if present, I have already pronounced judgment on the one who did such a thing. When you are assembled in the name of the Lord Jesus and my spirit is present, with the power of our Lord Jesus, you are to deliver this man to Satan for the destruction of the flesh, so that his spirit may be saved in the day of the Lord.
