"Ministry in the Spirit"

Lately I've seen several large churches advertising a "school of supernatural ministry" -- they even seem to have that exact title everywhere. I know people who have attended them, who report good results in their lives. And since this is Pentecost season, I've been studying and praying over the descriptions in the Bible of the Holy Spirit working in peoples' lives to do God's will. But after reading the life of Jesus and the book of Acts, in particular, I have to ask a question
if I may:  Is there any other kind of ministry? 

Jesus did his ministry in the power of the Holy Spirit (see Luke 4, especially verses 1 and 14). Luke 5:17 says specifically, "the Lord’s healing power was strongly with Jesus." If we're talking about instantly healing someone's illness without medical assistance, there's no way to do that except supernaturally, that is, through the power of God. The apostles, too, as they went on their first mission trip (Luke 9) were given "power and authority" to heal and cast out demons. As we know, Jesus told them to wait for the power of the Holy Spirit before becoming his witnesses (Acts 1:1-8).  And the phrase "filled with the Holy Spirit" is found seven times in Acts, plus similar references to the Holy Spirit's power in other places. 

So why would we talk about "supernatural ministry" compared to another kind? Perhaps it is to emphasize that we humans try things on our own strength (like designing our own workout program, instead of getting a trainer involved). Proverbs 3:5-6 would apply here; leaning first of all on God's wisdom and not our own motivations and opinions. In this case, if we don't start by recognizing our absolute dependence on the power of the Spirit, we can charge out there and try to do something and of course it doesn't work out. Obeying Jesus by joining in his mission means discerning where he is and what he's doing, first of all, and that is a supernatural event all by itself.

The disciples prayed together for ten days between Jesus ascending to heaven and the Holy Spirit's arrival. Likely, they prayed for understanding of the will of God and wisdom for this new gift that was coming. We too must pray earnestly, and perhaps long like the early church did, before trying to do something for God. In order to know what God wants done, and how and where to do it, the Holy Spirit must move in us and make us aware of God's will. Then the power of God will work in and around us to do what he wants done. Is that "supernatural ministry?" Yes, it is. More broadly, it appears to be the only kind of ministry to bear the kind of fruit God is looking for.
