Faith

As all the details of the trip have come together and the Lord has provided abundantly I still sit here and go "what about when I get back Lord." Where will I live and where will I work. I feel I want to finish school up and trying to afford an apartment and paying for school I always seem to come up short on that. So why do I not have the faith to know that the Lord will provide what I need when I return. How do I so quickly forget how the Lord takes care of me and provides what I need. Any thoughts on this?
