2Pe 1:5-7  And beside this, giving all diligence, add to your faith virtue; and to virtue knowledge;  (6)  And to knowledge temperance; and to temperance patience; and to patience godliness;  (7)  And to godliness brotherly kindness; and to brotherly kindness charity.

• Brotherly kindness is not just commanded but it is practical.
• We need each other. 
• A single member of the body is not much good by itself.
