Brethren: adelphos - true brothers, comrades, and partners 

The word ”brother” emphatically declares that it’s not really how well you fight in life that counts.  What really counts is that you keep on fighting!  So don’t give up on yourself, and don’t give up on those believers around you who seem to be struggling.  As long as they keep on trying—as long as they stay in the battle—they’re worthy of your friendship! 

I charge you by the Lord that this epistle be read unto all the holy brethren.   (I Thessalonians 5:27)
