"I think most Christians hear these urgent calls to do more (or feel them internally already) and learn to live with a low-level guilt that comes from not doing enough. We know we can always pray more and give more and evangelize more, so we get used to living in a state of mild disappointment with ourselves...We have to be okay with other Christians doing certain good things better and more often than we do." - Crazy Busy, DeYoung, p47.
Part of this guilt comes from an over-individualistic spirit and lack of a commitment to the local church body. We are members of a body incarnate that has multiple gifts and talents, time and opportunities. The answer to what needs to be done is not an answer for the individual only, but for the church corporately and also for her members.
