Olivia Munn gave her life to the Lord at TAM when she was 14. Now she's 22 and prepping for full-time ministry. She preached to her former peers (though some students were older than her). Her sermon challenged them to be bold for the Lord. She said if someone said she was hit by a Mac Truck you wouldn't believe her unless there was evidence. When we encounter the Lord, who is exponentially more powerful than a Mac Truck there should be evidence of it. When Olivia called people forward to exemplify that power boldly to those around them the altar was flooded.
