I recently discovered a wonderful Catholic speaker, Marino Restrepo, who after 33 years away from the church, returned to God after a mystical experience with Christ which he received during a 6 month abduction by Columbian revolutionaries. He is powerful and moving. I recommend that you watch first his personal testimony .The two versions contain some of the same ideas, but are filled with different details--so you may want to view both of them. The second one [with the red background] gives more details on his Illumination of Conscience and Vision. Of the other talks, I recommend most SPIRITUAL WARFARE, parts 1 & 2, then RADICAL CHANGE.
