When we first become Christians, we're spiritual newborns. But as we grow in our relationship with God, we reach a point of "adolescence" where we begin to think we can do things on our own. The trouble is, the more we develop the rebellious attitude that goes along with adolescence, the worse off we are in the Body of Christ. At some point, we need to mature spiritually into fully-grown adults, take responsibility, and do our part in the work of the Church.
