I admire people who give generously to those in need or to worthy causes but do so anonymously.
Not that I have that much to give, but when I do I shut up about it and try not to pat myself on the back.
I suspect that most freepers feel the same way as I do.
There’s no fixed rule except give glory to God. That’s what our Lord purposed to illustrate. Some folks take illustrations as wooden directions and ending up patting themselves on the back for THAT worse than they’d risk by commending it to God out loud whilst giving it.
