I do not know about other people but our family gives because its the correct thing to do being Biblical and all.
The charitable deduction is not the reason.
God loves a cheerful giver. So get cheerful about your giving and not a care to the deduction. Government Charity has so many strings attached, and it will get worse, that any Christian organisation ought to avoid Govt. money like the plaque.
Ditto that. I have never claimed the charitable deduction for my giving. Charity should be charity.....not tax avoidance.
