Everything we have is God's. We are called to manage those resources and advance the Kingdom of God. A 10% tithe is a step in learning to trust and obey God. It is a process by which we learn to live dependent on God for everything.
Far too often the argument is that we can't afford to do it. The point of tithing is doing it when you can't do it so you learn that it is only through God that you survive.
This is my point. If you don't believe that God will provide what you need in order to serve Him then you don't believe the God of the Bible. You might end up homeless but if you are obeying God then you are in the right place.
In america even the homeless are like the rich man. We have so much it is hard to think about how we can serve without having our things.
I have lived my challenge. I went 6 months without income and had huge bills from a business I closed. Paying tithe meant not buying food or paying another bill. We paid our tithe on the money we were pulling out of retirement accounts or on the gifts we got from friends. Somehow we paid all of our bills on time and did not starve. At least one time we tithed and recieved a gift from our church that allowed us to buy food. Why didn't we just keep the money? Because it wasn't about the money it was about trust and letting God be in complete control of our lives to the very point that we could not eat without the saving grace of Jesus Christ.
Another time we were called to give up our house and move to a new location and move in with another family because we had no home and no jobs. We served God and have been richley blessed. My family does not have nice cars or a nice home. We don't take vacations to nice places or buy nice things. We haven't been to a movie in years and we don't have cable. We get insurance from the state for our children and go without insurance for my wife and I.
Now I serve as a bivocational pastor. I work at least 30 hours a week in the church and my wife works at least 5-10. Should we count that as our tithe? We don't get paid by the church other than a $50 a month reimbursement account. We are in fact one of the largest tithers in our church. We were the second largest giver for faith promise next to our pastor.
Don't I have a valid claim that I don't need to tithe? I am poor. I do not have any excess. I am dependent upon the charity of others.
You can claim theological studies and positions and you can claim what Jesus did or didn't do about the law, but I will say with full conviction that if you are not willing to surrender all of your resources to God then you do not trust God with your life and you fail to understand God.
You can claim that 10% isn't applicable and is legalistic. I tell you it is a part of our transformation in that it is a part of our learning to give everything to God. 10% isn't the goal it is the training wheels of total submission.

Mark 10 and tell me how you are going to theologically explain how Jesus is going to let you keep that house and not use it to glorify God. Read it and tell me why you should get to keep your boat or motorcycle or other toys and use them only for your pleasure and not as a resource for developing relationships that allow you to develop opportunities to disciple others and advance the Kingdom of God.
Tell me why it is ok for you to sit on a lake fishing or whatever it is you do with your riches and not use those same resources to reach the lost? Personal restoration? Building family relationships and the discipleship of your family? To a limited degree but at the expense of everyone else?
It really is very difficult for the rich to enter the Kingdom of Heaven. That isn't just heaven. That is a current totally sold out slave to master relationship experience with Jesus Christ. When you have resources and the ability to survive financially you don't need Jesus unless you have some emotional distress. When you give everything you have, every dime, every object, every relationship to Jesus then you only survive because Jesus provides you saving grace every monute of every day.
That my friends is Sanctification. It is living in such a way that no matter what you have or where you are, everything is Gods. We love because God provides it. We act because God shows us. Every action, every step is taken out of obedience to God.
God does bless some with wealth and they have a huge responsibility to invest those resources so that they will benefit the Kingdom of God. Along the way that family may benefit from the comfort of those resources, but they will also have their own struggles because of that wealth and comfort. They will have a harder time living dependent on God. Not that they can't, but that it is harder.
Should a person with no job and no money tithe? Yes. Tithe on whatever God gives you. If you are sitting in the gutter and are homeless and someone else with a greater need sits next to you, then give them your shoes.
I would rather be in the worst place imaginable with God then the best place imaginable without God. God doesn't promise that you won't suffer. God promises you will have what you need to serve Him. Sometimes we are called to have little so that we can serve in a specific place in a specific way at a specific time.
Are you unwilling to serve God unless you have comfort? Then why would you be unwilling to give? Do you say "I will give, but don't tell me I have to give"?
Our church won't kick you out if you don't give. But I will tell you that you don't know God if you don't. The only way to really know God is to be totally dependent for everything, even your next bite of food.
