The Descent of the Holy Spirit

When the day of Pentecost came it found them gathered in one place. Suddenly from up in the sky there came a noise like a strong, driving wind which was heard all through the house where they were seated. Tongues as of fire appeared, which parted and came to rest on each of them. All were filled with the Holy Spirit. They began to express themselves in foreign tongues and make bold proclamation as the Spirit prompted them.
