2 Corinthians 12:12-13 Truly the signs of an apostle were wrought among you in all patience, in signs, and wonders, and mighty deeds. For what is it wherein ye were inferior to other churches, except it be that I myself was not burdensome to you? forgive me this wrong.

There were wrought in the church in Corinth many signs and wonders and mighty deeds. God’s power was manifested through the ministry of his servant, the Apostle Paul. There was no less of these mighty workings of God in the Corinthian church as there were the other churches founded. Indeed, the Lord instructed him to stay on in Corinth after the initial period where souls were won to God’s kingdom. He stayed for one year and six months. Amidst much opposition, he persevered.
