The right thing to do is to tithe. I understand why you may feel the way you do, but go to the scriptures to get your answer. The bible explains it plainly and clearly. Scripture does not state that only members of the body are to tithe. The tithe is the Lords. Whether you believe or not. Whether you go to church or not. The tithe is the Lords and His alone. The right thing to do is to obey God, always. I've included a few scriptures for you to study but there are sooooooo many more.
Malachi 3:8-10
8 "Will a man rob God? Yet you rob me.
"But you ask, 'How do we rob you?'
"In tithes and offerings. 9 You are under a curse—the whole nation of you—because you are robbing me. 10 Bring the whole tithe into the storehouse, that there may be food in my house. Test me in this," says the LORD Almighty, "and see if I will not throw open the floodgates of heaven and pour out so much blessing that you will not have room enough for it.
Leviticus 27:30
30 " 'A tithe of everything from the land, whether grain from the soil or fruit from the trees, belongs to the LORD; it is holy to the LORD.
2 Corinthians 9:6-7
6Remember this: Whoever sows sparingly will also reap sparingly, and whoever sows generously will also reap generously. 7Each man should give what he has decided in his heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.
Giving what belongs to God to the world.
Hosea 2:8-10 (New Living Translation)
8 She doesn’t realize it was I who gave her everything she has—
the grain, the new wine, the olive oil;
I even gave her silver and gold.
But she gave all my gifts to Baal.
9 “But now I will take back the ripened grain and new wine
I generously provided each harvest season.
I will take away the wool and linen clothing
I gave her to cover her nakedness.
10 I will strip her naked in public,
while all her lovers look on.
No one will be able
to rescue her from my hands.
1 Samuel 15:22
22 But Samuel replied:
"Does the LORD delight in burnt offerings and sacrifices
as much as in obeying the voice of the LORD ?
To obey is better than sacrifice,
and to heed is better than the fat of rams.
I love the way the NLT states it from Jesus himself.....
Matthew 23:23 “What sorrow awaits you teachers of religious law and
you Pharisees. Hypocrites! For you are careful to tithe even the
tiniest income from your herb gardens,[a] but you ignore the more
important aspects of the law—justice, mercy, and faith. You should tithe, yes, but do not neglect the more important things.
