Nice opinion, for you to be sure.
But since the date is not set in Scripture and it isn't Jesus telling us He's coming back Sat, then no believer is under any obligation to turn over anything to anyone.
God we trust. Man? Not so much.
Besides, once the rapture happens and all believers are gone, their stuff will be up for grabs, first come, first served.
You can then go and help yourself to anything left behind.
It always amuses me what non-believers can think of for believers to do to *prove* their faith to them. Turn over all our possessions to you. Fat chance.
I'd give it to someone less greedy first if I really though that way.
So now I'm greedy since I call out that September 23 prediction to be nothing but crap?
Spare me the lecture and get off your high horse........sheesh!
