Relying on faith in times of trials

Pastor Mark Buchanan once contemplated, "how much night can a day hold and still be called 'day'?" As a Christian there are times when I am reminded that I haven't fully put my trust in Christ. Those times are often when, as in my last post, I have been frustrated because of outside circumstances, mostly beyond my control. In those times, it feels as if there is far too much darkness in my days. I can sometimes (not often though) become the harbinger of negativity, which is a role I fundamentally despise. I was reminded of that today by my friend, Nancy, who like my wife, also suffers from RA. Additionally, putting negativity out there where others may feel its effect is something I clearly don't like doing, because as a fairly optimistic realist, I prefer to uplift.
And yet it happens. Because everyone needs to vent at times. I believe though, that when the venting takes over and becomes the majority of a persons reflections on life, that something is missing. In my case, what usually is missing is putting my trust in God--not, as my Pastor, Bryan Hurlbutt says, in his works--but instead, in his character.
Sadly, those of us who are believers tend to forget God in our times of great anguish, just as Job was reminded by his friend in Job 35:9-11:

Because of the multitude of oppressions they cry out; They cry for help because of the arm of the mighty. But no one says 'Where is God my maker, who gives songs in the night, who teaches us more than the beasts of the earth and makes us wiser than the birds of the heavens'? NASB

I am guilty of this. It's a learning curve, and I'm sorry that others have to feel the brunt of my ignorance. It makes me snarky and negative all in the interest of self-protection. It assuredly isn't my natural state, and the good Lord will help me through it. I've just got to remember that He's there for me. Trying to do it alone, through our own force of will is a fool's errand. That and remembering that it's never really as dark as it could be. There are people with a lot more trials than I have, and I grateful I have mine instead.
God is great. He will help us all through this. Rely on Him.
