Spiritual exhaustion happens to all of us. The reasons for it can vary but it is most likely that we have begun to look for joy in all the wrong places. Joseph's brothers were exhausted with guilt and shame. They were sorry for the evil they had caused Joseph but were under such guilt and shame that they believed Joseph would condemn them to slavery or worse. We often approach God in the same way. Our shame, guilt, or the evils done to us weigh us down and we try to please God on our own. But Jesus has offered us rest from this kind of religion.
