God did extraordinary miracles through Paul

Acts 19:1-12
Paul said, “John’s baptism was a baptism of repentance. He told the people to believe in the one coming after him, that is, in Jesus.”  On hearing this, they were baptized in the name of the Lord Jesus.  When Paul placed his hands on them, the Holy Spirit came on them, and they spoke in tongues[b] and prophesied.  There were about twelve men in all.
But some of thembecame obstinate; they refused to believe and publicly maligned the Way. So Paul left them. He took the disciples with him and had discussions daily in the lecture hall of Tyrannus. This went on for two years, so that all the Jews and Greeks who lived in the province of Asiaheard the word of the Lord.
God did extraordinary miracles through Paul.
If Paul could win the people of Ephesus to the Christian faith the news would spread through the whole province of Asia. Verse10 indicates that this is just what happened. It is likely that all seven churches mentioned in Revelation 1:11, as well as those  at Colossae and Hierapolis, were founded during this period.
Why?
John's baptism was a baptism of repentance, but Jesus Christ's baptism is the Holy Spirit. So their life were changed from their heart.
When meet obstinate people and refused to believe, then left them. This is the strategy to preaching gospel.
Paul did many wonders and healed the sicks, all of these is God did it through Paul, so give praise to the Lord, we are his servant.
How?
May I could like Paul to be good tool of the Lord, serve the Lord with all my heart, soul and strength.
