2COR-Chapter 13

Verses 1-14
Chapter 13
A WARNING, A WISH, A HOPE AND A BLESSING (2 Corinthians 13:1-14 )
13 For the third time I am coming to you. Everything will be established in the mouth of two or three witnesses. To those who have already sinned and to all others I have already said, and I now say, just as I said it when I was with you on my second visit, now I say it while I am absent, that if I come to you again, I will not spare you. I will take decisive action because you are looking for a proof that Christ really is speaking in me, Christ who is not weak where you are concerned, but who is powerful among you. True, he was crucified in weakness, but he is alive by the power of God. Keep testing yourselves to see if you are in the faith. Keep proving yourselves. Or do you not recognize that Jesus Christ is in you--unless in any way you are rejected? But we pray to God that you should do no evil. It is not that we want a chance to prove our authority. What we do want is that you should do the fine thing even if that means that there will be no opportunity for us to prove our authority. For we cannot do anything against the truth, but we must do everything for the truth. For we rejoice when we are weak while you are strong. For this too we pray--your complete perfecting. The reason why I write these things when I am absent is so that when I am present I may not have to deal sternly with you according to the authority which the Lord gave me to use to build up and not to destroy.

Finally, brothers, farewell! Work your way onwards towards perfection. Accept the exhortation we have offered you. Live in agreement with each other. Be at peace. And the God of love and peace will be with you. Greet each other with a holy kiss.

All God's dedicated people send you their greetings.

The grace of our Lord Jesus Christ, and the love of God and the fellowship of the Holy Spirit be with you all.
In this last chapter of the severe letter Paul finishes with four things.
(i) He finishes with a warning. He is coming again to Corinth and this time there will be no more loose talk and reckless statements. Whatever is said will be witnessed and proved once and for all. To put it in our modern idiom, Paul insists that there must be a show down. The ill situation must drag on no longer. He knew that there comes a time when trouble must be faced.
(ii) He finishes with a wish. It is his wish that they should do the fine thing. If they do, he will never need to exert his authority, and that will be no disappointment to him but a deep and real joy. Paul never wanted to show his authority for the sake of showing it. Everything he did was to build up and not to destroy. Discipline must always be aimed to lift a man up and not to knock him down.
(iii) He finishes with a hope. He has three hopes for the Corinthians. (a) He hopes that they will go onwards to perfection. There can be no standing still in the Christian life. The man who is not advancing is slipping back. The Christian is a man who is ever on the way to God, and therefore each day, by the grace of Christ, he must be a little more fit to stand God's scrutiny. (b) He hopes that they will listen to the exhortation he has given them. It takes a big man to listen to hard advice. We would often be a great deal better off if we would stop talking about what we want and begin listening to the voices of the wise, and especially to the voice of Jesus Christ. (c) He hopes that they will live in agreement and in peace. No congregation can worship the God of peace in the spirit of bitterness. Men must love each other before their love for God has any reality.
(iv) Finally, he finishes with a blessing. After the severity, the struggle and the debate, there comes the serenity of the benediction. One of the best ways of making peace with our enemies is to pray for them, for no one can hate a man and pray for him at the same time. And so we leave the troubled story of Paul and the Church of Corinth with the benediction ringing in our ears. The way has been hard, but the last word is peace.
