Faith My Eyes

Lately I've been dealing a lot with completely trusting God. Actually this one prayer request in particular I have been trusting God with for around 5 years. Why is it that some days are so easy to just bask in God's word and be able to say yeah I trust him and I'm not going to worry about it while other days it hits you like a brick the minute you get out of bed? I know that I have grown through this whole situation but I fear at times I make God sad at how I say I trust him but yet I give in to letting my mind fill with worry and fear. Its something I'm really having to learn that if I say I trust him then my actions need to reflect this as well. And why is it such a temptation to think well God has really let me down by not giving me EXACTLY what I wanted when in reality he has given me more than I could ever hope for if I take a step back and look at the entire situation. I need to do that on a daily basis I guess....put perspective on my life and how good I have things even though this one little situation in my mind is whats ruining everything. And I know that is just how life is, once we have one situation taken care of there will come another one that requires faith as well and I guess I'll need the strength and hope that came from this struggle to make it through that one.
