There is no indication to suggest that there was sickness in the Garden of Eden before the Fall. Neither is there any evidence in the life of Christ that sickness is ever God’s desire unless it is to bring glory to the Father (see John 9:3). The book of Revelation anticipates a time when the dwelling place of God will be with men so that ‘there will be no more death or mourning or crying or pain’ (21:4). But until that day, we live in the gap between the Fall and the coming redemption of all things. And so, we still sometimes may get sick, our businesses may fall foul or world markets, our homes may be flooded, and so on.
Of course, occasionally, a miracle breaks in: The storm calms, the train leaves early, an anonymous gift comes through the door, the blind man sees, the fishing line comes with hooks. And when these things happen, we are granted a tantalizing foretaste of the new creation in which all things will conspire with unbounded complexity to perpetuate beauty and harmony for the glory of God.
