When Pentecost Day arrived, they were all together in one place. Suddenly a sound from heaven like the howling of a fierce wind filled the entire house where they were sitting. They saw what seemed to be individual flames of fire alighting on each one of them. They were all filled with the Holy Spirit and began to speak in other languages as the Spirit enabled them to speak.

In the last days, God says,

I will pour out my Spirit on all people.

Your children will prophesy.

Your young will see visions.

Your elders will dream dreams.

Even upon my servants, men and women,

I will pour out my Spirit in those days,

and they will prophesy.

-- Acts 2:1-4, 17-18, Common English Bible
