Is lack of healing a failing of the church to exercise authority for their king?

In response to a reader’s question, I suggest a moderate path between taking kingdom theology to humanistic extremes that presume upon God’s authority, and swinging so far the other way that we refuse to represent his authority at all.

Christianity, confidence, and certainty

We can have complete certainty in the existence of God, and a high degree of confidence in the truth of Christianity specifically. This is justified not only by philosophical, prophetical and historical arguments, but especially by the direct knowledge imparted by the Spirit of God.
