Aired 09/11/2011. Sermon: On September 11, 2001, as thousands of people entered their offices in the World Trade Center buildings and the Pentagon, and others boarded a plane bound for Los Angles, little did they realize that this would be their last day in this life. What is the most important lesson we can learn from this great disaster? Feature: A tribute and memorial on the 10th anniversary of the 9/11 attacks on America. We'll meet some of the survivors and hear from some of those involved in the rescue operation, and learn how all of this affected their lives.
