As we’ve seen before in Acts, our spiritual enemy Satan opposes the spread of the gospel of Jesus Christ.  Satan cannot stand it when the name of Jesus Christ is exalted and the message of Jesus Christ is spread.  So, once again, this time in Ephesus, Satan stirs up opposition to the message of Jesus, so much so that a riot breaks out.  Satan’s opposition and work in Ephesus in the past is repeated all over the world today in places like North Korea, Somalia, China, Iraq, Iran, Afghanistan and even in the U.S.  But, just like in Ephesus, Satan is no match for the power of God and the gospel of Jesus Christ.  Ultimately, God wins and the gospel spreads, though not without struggle and hardship.
