2 Corinthians 13:9-11

9For we rejoice when we may be weak and ye may be powerful. But this also we pray for, your perfecting.

10On this account I write these things being absent, that being present I may not use severity according to the authority which the Lord has given me for building up, and not for overthrowing.

11For the rest, brethren, rejoice; be perfected; be encouraged; be of one mind; be at peace; and the 1God of love and peace shall be with you.
