Passion 07 was a huge college gathering in Atlanta, Georgia in which 22,000+ Christian high school seniors and college students came together to worship the Lord. There this event was spread over 2 venues to encompass all of the attendees. There was free time to experience a prayer walk and small groups also known as family groups. They had a group lunch in which all 22,000 people had box lunches together and a candle light ceremony in which all the attendees walked silently through the streets to a stage outside. There they had a candle lighting service and sang praises together.
