Acts 19 Paul's third missionary journey took Paul through some of the places where churches had been established. He encouraged and strengthened the believers all through the region of Galatia which would include Derbe, Lystra, Iconium. He also traveled through the region called Phrygia in Asia Minor. This would include the cities of Laodicea, Colossae, Philadelphia, Thyatira, Sardis and Ephesus.
In Ephesus, Paul found some "disciples". These 12 men had been baptized with "John's baptism". They had not heard of the Holy Spirit. Paul taught them and the Holy Spirit came on them powerfully so that they "began speaking in tongues and prophesying." Paul spent 3 months speaking in the synagogue in Ephesus and then about 2 years in Ephesus teaching in the "school of Tyrannus." Verse 9 tells us that Paul "took away" or separated the disciples from those who rejected the gospel of Jesus Christ. What an education the believers got to receive there!
The Lord worked through that group of believers so much that "all who lived in Asia heard the word of the Lord, both Jews and Greeks." The Lord also did many miracles there through Paul. Even handkerchiefs or aprons that Paul touched were taken to the sick and they were healed! Evil spirits were also being cast out in the Name of Jesus.
When some Jewish exorcists tried to use the name of Jesus saying, "I adjure you by Jesus whom Paul preaches." the demons responded with, "I recognize Jesus, and I know about Paul, but who are you?" Then the man who had the evil spirit attacked and overpowered the men attempting to do what only God can do.
God was also working in the lives of the many people in Ephesus who were involved in magic practices. They would confess their practices, burn their books, and magnify the name of Jesus.
"So the word of the Lord was growing mightily and prevailing." (v 20)
One more thing that happened in Ephesus as the Lord was at work building his church : the craftsmen who made silver shrines to Artemis, the goddess whose temple was located in Ephesus, became upset that their businesses were seeing less profit as people turned away from the false religion to the One True God. They caused a riot that "filled" the city. When it was finally calmed down by the "town clerk" everyone was sent away. After this, Paul departed for Macedonia.
Father in heaven, may the word of the Lord grow mightily and prevail in our cities and towns today. Send Your Holy Spirit with power to anoint Your followers.. to bring healing and deliverance to those in need. Open the eyes of people to recognize the evil of magic and false gods so that they repent and come to know Jesus Christ the Lord.. Purify Your church and teach us Your Word so that we come out from worldly and wicked influences and be strengthened in Christ Jesus our Lord and Savior. Let Your Kingdom come and Your will be done on earth.. in us.. as it is in heaven. We ask all these things in the Name of our Lord Jesus Christ, Amen.
