You are correct because the operative word is "seeking signs". No ministry what won thousands to Christ, either in the Evangelical, Holiness, or Pentecostal movements ever sought signs and wonders as their first priority. They sought souls for Christ. If you look carefully at the ministries of Jonathan Edwards, Charles Finney, William Seymour, Edward Irving, Maria Woodworth-Etter, Kathryn Kuhlman, you will see that their first priority was to win souls for Christ. That was their passion. The signs and wonders that came were a byproduct of the power of God that came as the result of the preaching of repentance. This put signs and wonders at God's discretion not theirs. The first sign of the power of God being present is the conviction of sin and unbelievers crying out to God for mercy and salvation. This is what happened with Maria Woodworth-Etter. When she had her tent meetings, unbelievers up to 20 miles away were convicted of their sin and came almost running to her tent to receive Christ.
When It says that Paul preached the gospel among the pagans with signs and wonders in Acts, the signs and wonders happened among the pagans to show that the power of Christ was greater than that of their own demon gods, and to draw them to Christ. There is no evidence in Acts that signs and wonders happened in the Christian meetings. They happened out among the pagan unbelievers. When the group under persecution in Jerusalem got together and prayed, the place was shaken, they were all filled with the Spirit, and spoke the Word with boldness - to whom? The unbelievers of course! They asked that signs and wonders be done in the name of Jesus. Where? Among the unsaved! So, when there is a "full-gospel" crusade in your town, who are the ones who attend it? 90% Christian believers and those they invite to it. I attended a massed crusade a couple of years ago in Auckland with 2000 people in the church building. Most were Christians. There were around 40 people who came for to receive Christ. A large crowd came forward for their "touch from God". I didn't see any signs and wonders, although some said it was a great meeting with wonderful results. It is interesting that the preacher did have thousands come to Christ in Africa when he had over a million unbelievers gather in a large field to hear the gospel. In Auckland, he basically preached to the choir!
John G Lake, a pioneer Pentecostal, had remarkable results when he went to South Africa and preached the gospel to mainly unbelievers. Smith Wigglesworth was the same, his passion was for souls for Christ, and the remarkable healings resulted in thousands turning to Christ. Maria Woodworth-Etter did not want to pray for healing at first because she felt it was a distraction from her gospel preaching. The Lord assured her that if she prayed for healing, even more souls would come to Christ, which they did.
These are so far different from the "mega-churches" full of believers, seeking for and pretending that signs and wonders are occurring in those churches. When in the book of Acts, and in any subsequent revival, the signs and wonders happened among unbelievers under the preaching of repentance. In the Welsh Revival, they did have to lay off great numbers of the police force in some areas, because of the significant reduction of crime, and many bar owners went out of business, because fewer people patronised them.
So, if people are seeking signs and wonders in their churches, they are barking up the wrong tree. They would be better off praying that the power of God would go with them as they got out where the unbelievers are and shared the gospel with them. Instead of praying, "Lord bring signs and wonders into our church", they should be praying, "Give us boldness to share Your gospel to the lost and let signs and wonders be done [among the lost] in the Name of Jesus."
