I already gave you a warning when I was with you the second time. I now repeat it while absent: On my return I will not spare those who sinned earlier or any of the others,
NIV
I have already warned those who sinned formerly and all the rest also, and I warn them now again while I am absent, as I did when present on my second visit, that if I come back, I will not spare [them]AMP
I told you before, and foretell you, as if I were present, the second time; and being absent now I write to them which heretofore have sinned, and to all other, that, if I come again, I will not spare:
KJV
Now we pray to God that you will not do anything wrong. Not that people will see that we have stood the test but that you will do what is right even though we may seem to have failed.
NIV
But I pray to God that you may do nothing wrong, not in order that we [our teaching] may appear to be approved, but that you may continue doing right, [though] we may seem to have failed and be unapproved.
AMP
Now I pray to God that ye do no evil; not that we should appear approved, but that ye should do that which is honest, though we be as reprobates.
KJV
This is why I write these things when I am absent, that when I come I may not have to be harsh in my use of authority – the authority the Lord gave me for building you up, not for tearing you down.
NIV
So I write these things while I am absent from you, that when I come to you, I may not have to deal sharply in my use of the authority which the Lord has given me [to be employed, however] for building [you] up and not for tearing [you] down.
AMP
Therefore I write these things being absent, lest being present I should use sharpness, according to the power which the Lord hath given me to edification, and not to destruction.
KJV
We are glad whenever we are weak but you are strong; and our prayer is that you may be fully restored.
NIV
For we are glad when we are weak (unapproved) and you are really strong. And this we also pray for: your all-round strengthening and perfecting of soul.
AMP
For we are glad, when we are weak, and ye are strong: and this also we wish, even your perfection.
KJV
