God's Financial Plan!
Tithing is God’s financial plan for you. The money you spend for lunch today will last about four hours. Money spent for a car will last 36 months, maybe. But money spent for the kingdom of God will last forever. The Bible says to lay up for yourselves treasures in heaven. The day is going to come when all that you will have is what you’ve given to God.
Why should I tithe? Because God commands it. The Bible says to bring all the tithes into the storehouse. Not “if you feel led.” He says do it. Do you pay the IRS because you feel led? No, you do it because it is the law.
If you don’t tithe, God sees you as a crook.
If you don’t believe that, read the ninth verse of Malachi 3. “Ye are cursed with a curse: for ye have robbed me.” I didn’t write that, God did. If you don’t give, you are living under a curse. You will work harder and make less. You will financially struggle regardless of your income. Whatever you make, it will not be enough. Why? Because you’re in rebellion to the will of God.
You say, “Look, I know a guy who never tithes and he’s rolling in money.” No, you don’t. You know a guy who’s storing it up so he can pay the Methodist hospital where a surgeon will split him open like a field dressed deer and get all his money in one day.
The people who prosper long term, are the people who obey God’s word and who qualify for success according to his principles.
Tithing is how taxation came to exist! If God is the almighty and powerful why would he need money (which is a creation of man) given to him by a mere mortal man? Think about it logically and not superstitiously and you'll come to a good answer.
