"He makes the whole body fit together perfectly. As each part does its own special work, it helps the other parts grow, so that the whole body is healthy and growing and full of love." Eph 4:25-16. Involvement can't be legislated - you can't make it an issue of obedience. It is essential every "part does it's share in building up the body"... that we realize WE have a contribution to making the Body healthy, and in changing our world.
