God will recompense rest to the believers that suffer and tribulation to those that trouble them.  That’s why the Bible says elsewhere not to take vengeance on those that do you wrong.  God will totally deal with them.  Next, the people of this church were freaking out about something.  What were these folks afraid of?

-They thought the Tribulation of Revelation had started-

-They thought they had lost their salvation-

-They thought Paul had kicked the bucket-

-They thought they had to get circumcised to be saved-
