Paul went to Ephesus on his missionary journey. When he arrived there he found disciples there who had believed. They had not heard of the Holy Spirit and had only been baptized with John’s baptism of repentance. Paul explained:

“John baptized with the baptism of repentance, telling the people to believe in the one who was to come after him, that is, Jesus.”” Acts 19:4 ESV

They were baptized and then Paul placed his hands on them to receive the Holy Spirit. Once again the Holy Spirit filled the people as He did on Pentecost:

“And when Paul had laid his hands on them, the Holy Spirit came on them, and they began speaking in tongues and prophesying.” Acts 19:6 ESV

God had not changed. He filled the believers in Ephesus with the same promised power and presence of the Holy Spirit. God has not changed still today! We are a part of the promise:

“For the promise is for you and for your children and for all who are far off, everyone whom the Lord our God calls to himself.”” Acts 2:39 ESV

Come Holy Spirit!
