Why are some blessed with lots while some have so little?

So, I was at my mom's today and she asked why I thought that some people had so much and some people had so little. I told her this was a question that plagues me often. A couple of years ago while driving home from work, I had a long talk with God about this subject. My husband Robbie and I have always struggled with money some, more at sometimes that others. We were at a particularly difficult spot. I was trying to finish school and needed to quit my job for a while to do it and Robbie just wasn't satisfied with his job either. There just wasn't enough money to do what we wanted to do and I asked God, "why can't we just have the money we need to be able to not have to worry? Other people have more money than they know what to do with and yet we struggle to make ends meet much of the time and never seem to have any extra. It's just not fair." In the midst of my pity party the answer came to me. If I had enough money that I never had to think twice about things like tuition for school, then I wouldn't have to trust Him to meet my needs. What God wants most from all of us is to bring glory to Himself. If I had a million dollars then I wouldn't really give him a chance to work things out in that perfect way of His, thus denying him the ability to draw others closer to him via my testimony.

After this discussion with my mom today, another question came to mind. On two occasions that I can think of off the top of my head we have been more than willing to drop everything (literally everything) and go where we thought God was leading us. In fact we were positive we were doing His will. Where did it leave us? The most recent time left us broke, temporarily without a place to live, jobless, and miserable. Why didn't God bless us for our efforts? Even if we weren't doing His will, if we thought we were and had the best of intentions shouldn't that have been enough to keep us from struggling so much?I haven't found the answer to this one yet but I know that there is one. I know that God works all things out for the good of His children. It is in this that I have found my peace.
