Most clearly the Christian steward is a steward of the Gospel. This is the greatest treasure with which he is entrusted. It must be his concern so to use all he is and has that the Christian message will be kept clear and will be sent forth freely and actively among men. It will be his purpose to cultivate the desire of others to share generously in such a concern. This is a part of the accounting due to his Lord in the stewardship which he holds.
