Spiritual Power is Dangerously Heady Stuff

Like sex, spiritual power is dangerously heady stuff. I remember praying with my wife for a two-year-old child in Malaysia. Her body was almost completly covered with raw, weeping eczematous areas. She ran around the room restlesslly so that her parents had to catch her to bring her struggling to us. We began to pray and extended our hands to lay them on her. The instant our hands touched her she fell into profound and relaxed slumber in her parents' arms. But ther was more to follow. I shall never forget our sense of exhilaration and excitement as the weeping areas began to dry up, their borders shrinking visibly before our eyes like the shores of lakes in time of drought. That was power!
A person who has never experienced the impact of such a sight has no idea of its effect on one's emotions. People have been known to laugh and cry helplessly for hours after observing miraculous power, especially if the miracle is a major one touching someone close to them.
If you ever exercise spiritual power of that order, if you should ever see a congregation of hundreds weeping in broken repentance as you preach, the experience may make sexual love seem as banal as eating ice cream. Small wonder that Jesus needed to warn the seventy when they returned full of excitement after their successful mission. To be sure, he had seen Satan fall like lightning from heaven. Yes, indeed, he gave them even more authority and power. "However, do not rejoice that the spirits submit to you, but rejoice that your names are written in heaven" (Lk 10:20).
There is danger in power. Sexual power can make some men rapists and some women nymphomaniacs. Spiritual power can be equally destructive. There is therefore danger in every revival. We must be careful to hold to Christ's own scale of values.
