Giving Money

My dad was chatting and says that true church will not ask you to tithe or give 10% of your income. Well, if you have the revelation, then you can give according to your generosity. But you cannot keep talking about money and compel people to give till it hurts. I am not a miser, I give offerings and used to tithe, but not anymore. Now I just give offerings on Sunday services. Financial giving is a very personal matter and preachers should not keep harping about giving till it hurts.
