Do you think it unreasonable for Jesus to ask for the 1st 10% of your gross income?

Well, you could say its generous of Jesus to give your your next breath, your lunch and your home. Do you deserve the money you get, or do you deserve the judgement of God on your sin? How kind of Jesus to let you keep 90% of your income, when it all belongs to him.

Anyway, if you don't buy all that, maybe Jesus would accept 9% of your post-tax income. That would be a step in the right direction.
