You are opening yourself up for more hurt if you give them $$$. The audacity! I would tell them to go ask for a loan from their "spiritual family", because after all, "Jehovah provides." I'm sure their loving Elders will gladly help them out!! Really, tell them to "go forth, be warm, and well fed."
My philosophy in life: I reciprocate what I receive.
Those shunning clowns wouldn't get one single nickel out of me. They'll take your money with no so much as a "thank you", then claim to their friends that it was Jehovah that provided for them. Then, they'll conveniently forget to pay you back, then shun you when you ask for it repaid.
I swear, if you loan them that money, you'll really get a taste of their "Christian Love". Don't do it! Like Nancy Reagan used to say, "Just say NO."
