Being "called out ones" gives a different perspective on what we identify as the "church". Rather than gathering in our temples and cathedrals, we are as the Seals in the Navy. We remain in the world but we are expected to perform at a much higher level.
Rather than focusing on programs and activities, the main emphasis should be impacting those who are hurting, no matter what the reason. All to often we recognize people for their God given skill and entertainment value than their involvement with the broken, impoverished, and alienated people.
