tithes can be a sensative subject. there are people that do not believe that it is a doctrine for the NT church. I believe it is somethign that is pre-law, and I liken it to marriage. It is so foundational, that it should be assumed.
for me, I take it a step further. I do't think there is scriptural reference, directly; but I, personally, don't want to do the "minimum". Tithe is the foundation of all my giving. and as the foundation, I want to "bolster" that foundation as much as possible.
In my case, and again, not something I would suppose others would do or accept, but just for example sake: I pay tithe not on gross, but on something more than gross. what I mean is that I pay tithe on a figure rounded up to the next $1000 of gross pay.
I have found that I can't aford to not pay tithes.
