Despite the fact that I am often critical of Christianity and religion in general, and despite the fact that I certainly do not take the Bible literally, I definately believe in angels.
Of course, I believe these angels are the people I loved who have died, and I truly think that they've come to save me and my friends on numerous occassions...
This is going to sound corny or fake as hell, but when I was 16 I lost a good friend unexpectedly. For a few weeks before he died, he often talked of death and what he'd do to show us if anything was "there" afterward. One thing he promised to do was to turn on this one particular lamp in my other friend's house.
Now this was kind of a big deal, because I'd known that friend for a number of years, and I'd known that lamp for just as long - the damn thing never, ever worked. You could change the lightbulb, change the socket, do whatever you wanted, it wouldn't turn on. Why the hell he decided to keep it, I have no idea, but he did.
Well, wouldn't you know it, the very same night my friend died we were all sitting in the other friend's room, faces towards the floor, and what happens? That light flickers on. And the lamp has worked ever since.
Can I prove my friend turned that on? No. It could have been some strange coincidence. But, for me, the timing and the result are all the proof I need.
(Course, I've got plenty of other signs over the years. You wouldn't believe the ways I or my other friends have been saved from death or deep, deep trouble by the most random occurances).
So, yeah, anyway, I don't believe in the Bible but I definately believe my buddies and family are still around waiting for me.
