Acts 2:1-4. There is a reason why this part of the bible (Pentecost) should be highlighted is if it’s repeated in an atmosphere of a believing people of faith and prayer the miracle happens again because God is present.
The Holy Spirit is the living memory of the church and he makes all things present, therefore the feast Pentecost, which in the scriptures is history, is present in the person of the Holy Spirit. He makes that memory become a present reality.
So the gospel is not just good history it is a present reality that we experience in the now.
