Christian brotherhood is not a bonus feature for men who have extra time. It is one of the ways God forms men who can stand, repent, lead, endure, and love well.

Isolation lets a man stay unchallenged. Brotherhood brings truth close enough to interrupt drift. That is why men need a band of brothers, not only casual friends.

Brotherhood looks like men meeting consistently, telling the truth, praying specifically, carrying burdens, and asking what obedience looks like now.
