The early church did not seek to formulate a theory of illness; instead, it healed the sick. It did not attempt to explain how the demonic could exist in a good world made by a good God; instead, they cast out demons. They had no hypotheses about how prayer works. They simply prayed… Their attitude was not anti-rational or anti-theological, but merely concrete. They looked, not for adequate ways to conceptualize the Kingdom, but for ways to actualize it.
