The Upper Room
This clipart image of men and women gathered with fire coming from heaven represents the Day of Pentecost as described in Acts 2:2-4. "And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting. Then there appeared to them divided tongues, as of fire, and one sat upon each of them. And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit gave them utterance."
