The outpouring on the Day of Pentecost was a special day for all believers in Jerusalem. Jesus had told the disciples to wait for the promised Holy Spirit. “Behold, I send the Promise of My Father upon you; but tarry in the city of Jerusalem until you are endued with power from on high” (Luke 24:49)
Having the Spirit in salvation and being filled with the Spirit are two entirely different events in a Christian’s life. When I would get around other Christians, I would sense a unity that was supernatural. The Holy Spirit was bringing this unity among my new friends. I also noticed that my prayer language was bringing harmony to my life with God. When I would pray in the Spirit, I would sense oneness with God and His plan for me. Also, when I would pray in the Spirit with others, I would sense that same harmony spreading among us. What were we all saying in our heavenly languages, I wondered? Later, the Lord Jesus explained to me that Pentecost was the reversal of the curse at the tower of Babel!
