Acts 19:20

“So mightily grew the word of God, and prevailed.] Over conjuring books, conjurers themselves, yea, even the devils; the power of God going along with it, many were converted; which is meant by the increase of it, and were delivered from the power of darkness, out of the hands of Satan, and translated into the kingdom of Christ. Beza’s ancient copy reads, the “faith” of God; and the Syriac version, “faith in God”.”

“So mightily grew the word of God - So powerfully. It had such efficacy and power in this wicked city. That power must have been mighty which would thus make them willing not only to cease to practice imposition, but to give up all hopes of future gains, and to destroy their property. On this instructive narrative we may remark: (1) That religion has power to break the hold of sinners on unjust and dishonest means of living. (2) That those who have been engaged in an unchristian and dishonorable practice will abandon it when they become Christians. (3) That their abhorrence of their former course will be, and ought to be, expressed as publicly as was the offence. (4) That the evil practice…”

“So powerfully did the word of God grow - In extent, and prevail - In power and efficacy. Acts 19:21”

“19:20 Luke’s summary of the success of the Good News in Ephesus is short but pungent (cp. 2:43-47; 5:14; 6:7; 9:31; 12:24; 16:5; see Rom 1:16). When the Christian faith overcame problems of internal dissension, idolatry, and pagan practices, it spread widely and grew rapidly.”
