To the author of the Facebook Group, "If you join our group, we will give one dollar to fight global poverty", who hopes a hundred thousand people will join the group so they can give $100,000 to fight global poverty:
Giving a hundred thousand dollars to fight world poverty is awsome and noble.
But why should such a God-led gift be used like a publicity campaign? Why should the gift be limited by people joining a group in Facebook?
If you want to give, then give.
If you want to promote assisting the poor, then do that.
But don’t make a bunch of people think that they are “helping the poor” by joining a Facebook group. It just isn’t true.
