We are not under the law any more and God loves us and reaches out to us even when we don’t keep it.
While I don’t have any problem with tithing, I wouldn’t advise it. He already knows out heart and our level of commitment to Him, and we don’t need to prove it to Him.
It almost smacks of trying to manipulate God, which is just doomed to failure anyway. He owes us nothing, even if we give everything we own to Him.
Navel-gazing study-group approved-insight addendum: (God gave you the tether.)
Everything we own IS His anyway.
