The New Testament vision of the essential work can be captured: to witness or to manifest what is going on in heaven
So you may declare the praise of him who called you out of darkness - 1 Peter 2:9
Wisdom of God should be made known to the rulers and authorities - Ephesians 3:10-11
Even if it must speak as a lone voice to a disobedient people - Isaiah 65:2
People usually form associations to deal with a single challenge
It also well known that associations tend to stray from their founding purposes
Second and third generation leaders often do not share the orginal vision, their work becomes a job rather than a mission
Officers are tempted to place their own interests above the orginal mission
Those interest tend toward unrelated purposes and many times are political in nature creating division among the group, at this point the mission is hijaked
