Well...all I gotta say is...Don't come around to my campus pub unless it's for a pint of cool ale and the usual harmless revelry.
But seriously.
1) You're intention of bringing peace and hope to peoples lives was good. Never a bad desire.
2). You're tactics may have been a bit much...but I dunno what they really were like. In general, it will freak people out if they're all in a pub and a group of folks just walk in and start telling everyone they're loved. The initial reaction will be ''What the...I'm outta here!"
3) No one knows why the pub closed down, as has been stated. Maybe God had a hand in it, maybe there were different factors. That really doesn't matter. This is what matters: If you think the actions of you or your group somehow moved God's hand...
I guess what I mean is, that from what I read on the Forums and in the chat from time to time, is a lot of people seem to develop this idea that they are God's special conduit through which lives are changed and souls are saved. Now, I am not doubting one bit that God can and does use us for his good ends...but if we are ever so graced to be used in such a way at all, we certainly can't chalk up one instances as blanket proof that everything else that goes the way we think it should is God's will...or that whatever we do, God wills it.
This leads down the path of a sort of spiritual narcissism...the sort of pride that made angels fall.
For all you know, maybe God liked the bar, most of the time. Maybe he didn't mind people having a beer and playing pool. Maybe the owner was donating his profits to a charity or some other good end. We don't know.
When something like this happens, don't say ''My, look at how we prayed and prayed, and evangelized, and see how God has answered our effort by closing it down!!'' Instead, approach it with this attitude: ''Well, that bar closed. They seemed a rowdy bunch. I hope that this improves the lives of its patrons and that the owner can continue to find steady employment for himself and his family.''
