Fighting the good fight

Lately I have been faced with some really tough and depressing situations. Things that maybe I knew where going on around me but I didn't really want to address, came face to face with me over the last week. Times like these make me wonder why God has let me be hit by such heartbreak and devestation. I mean I've already been going through so much already in the last six months, why more, why me?
Of course I come to remember that God does everything for His glory. If I feel as if I am going through "hell" now it is because through this situation He is molding me into the woman that He needs me to be. Since submitting my life to Him, I have wanted and committed myself to letting Him have His way. So then why do I complain when He does?
I have to realize that complaining and getting upset with God is not going to help nor is it going to take me out of this pit that I feel I am in. Trusting Him and His guidance through this is the only way I'll make it out of this with the new attributes He wants me to acquire during this time (the reason why He put me here in the first place...to gain qualities that will glorify Him through my life). And if I just give up then all of my pain and patience thus far is wasted.
Words that I cling to and that play over and over in my head are from Paul in the New Testament, he says simply to Timothy, "Fight the good fight of faith..." -1 Timothy 6:12
This life is going to be a battle. One that, as a Christian, I must fight. As long as I don't give up, as long as I don't lay down, I find victory in the end. I might become bloody, bruised, and feel like I am going to hit the mat any second, but as long as I don't give up and tap out, I get the Championship belt.
