When the day of Pentecost came they were altogether in one place.
And suddenly a sound came from heaven like the rush of a mighty wind and filled the entire house where they were sitting.
And there appeared to them tongues as fire, distributed and resting each one of them.
And they were all filled with the Holy Spirit and began to speak in other tongues, as the spirit gave them utterance.
This was a fulfillment of a promise Christ had left his disciples that he would send them a comforter.
Should Christians expect fulfillment of promises from God and even from other Christians?
