Yahweh is not only the Creator but the sustainer of all that is. To try to live without the Creator while holding onto the creation is folly. In the same way, to try to hold onto peace and joy without source of all peace and joy is folly. Humans were created to be joyful, but when we displace God from the throne of our life, joy goes with him. It can be no other way, because he alone is the source of all joy.
