Have you suffered so many things for nothing? – if indeed it was for nothing.

I fear for you that my work for you may have been in vain.

and by which you are being saved, if you hold firmly to the message I preached to you – unless you believed in vain.

Let no one who delights in humility and the worship of angels pass judgment on you. That person goes on at great lengths ¹  about what he has supposedly seen, but he is puffed up with empty notions by his fleshly mind. ² 

for it is God’s servant for your good. But if you do wrong, be in fear, for it does not bear the sword in vain. It is God’s servant to administer retribution on the wrongdoer.
