(ok, i guess i'm not finished posting) - relying on God

Sometimes I think about what it means to rely on God. My last post brought this to my mind because of the way I'm easing into this ministry work. I get to thinking, what if I just put my all into working on ministry stuff? Would God then provide for me? I think that He would, so why don't I just do that? Then I think about things like, there's no evidence of anything being there for me to do, so what would I fill my time with if I decided to jump in full-time with the ministry. And then there's the fact that I'm not good at managing my own time, so would I even be able to motivate myself to do the work? I suppose these things cannot refute God or stand up to His promises; the first is me not seeing what He might, and the second is my weakness. So what do I do? Well, I've already told these people that I'm going to help them out by working for them, so that's what I've got to do. But should I have done differently?
