I had this discussion today with a christian, who said that he thought one could...grant it he thinks he never can, but he has seen others. How one sees others I do not know? He uses only one verse for this Rev. 3:5. to back up his claim...seems there would be more? When I mentioned that God nevers leaves us nor forsakes us and that there is no way once the Holy Spirit comes in you can take him out, he is kind of there forever. Even David who wasn't "Filled" with the Holy Spirit, couldn't leave God no matter how often he tried to run from him. David said no matter where i go, to the East or the West, North or South - God YOU ARE THERE! He didn't know what to say to that. He say it is a mystery that we cannot explain...I had to disagree and said it was one of those truths that christians have that non believers do not. They are never sure where the bible says we can be sure and secure!
