When the Holy Ghost came down upon the 120 in the upper room, their lives were changed forever. They went from being fearful, uncertain, and guessing, to being empowered by the same Spirit that dwells within you and I – The Holy Ghost. His entrance was dramatic in the sense that it was a “sound” as of a rushing mighty wind.

Their (the 120) first message was “The Mighty Works of God” (Acts 2:11 Amp). It was preached in every language that was represented at that first Church service. All who heard were amazed, marveled, and in doubt. Some even mocked and ridiculed, but God was establishing His earthly headquarters from which He would operate.
Jesus said to the woman at the well, “…a time is coming when you will worship the Father neither [merely] here in this mountain nor [merely] in Jerusalem” (John 4:21 Amp). That time came on the day of Pentecost. The Church is not limited to a particular place, mountain, city, or building. The world is our platform. We are the Church individually and collectively.
