The key elements to this, of course, are:
Diversity-old, young, and in between; male and female; all races and ethnicities... in short, all the wonderful variety of the humanity God created.
Stewardship-God created and possesses everything in the world and the universe. We are called faithfully to manage his possessions.
Service-helping the needy, counseling the lost, aiding the broken hearted, etc. We are called to have a heart and lead a hand, to help our brothers and sisters out by helping them.
