Control Issues

So, this is probably not the best time for me to write this post. I have always found in the past it is best to let things "set" awhile before verbalizing my true emotions. That gives the Holy Spirit some time to work in my heart and get my motives right before I start babbling about how upset I am. There is no doubt in my mind (or in any of yours if you know me) that I struggle when things are out of my control. Now, I also am aware that this is an area that God has been refining in my life, and over years has worked on my heart in realizing that I have no control. He is in control. I know that, and I am not sure why He insists on continuing to teach me this lesson. Is it possible that I haven't learned it yet??? : )
So this evening I received another lesson from God in the fact that I have no control, that it is only important that my motives are right and that I am willing and actively serving Him, and that the rest is His responsibility. Something I had worked very hard and long on which I had really hoped would be a God-honoring ministry pretty much fell apart. I know God can work through these things, and I know it is His ministry, not mine, but I feel so disappointed.
I am processing so many emotions right now, and mostly just trying to figure out what God wants to teach me through this and how I can react without sin in my heart. It is astounding to me how God can take every situation and turn it into a "character-building experience."
