In Times of Heartache

There are times when its easy to believe that everything has a purpose and that everything happens for a reason. And there are other times when no reason is good enough and no bigger purpose can be seen. Times when life sucks and shit just happens. There are times when I think I know God, times when I think I know God's plan and I know where he's going with this world. Other times I have a hard time believing there is a plan at all. Its not that i have a hard time believing there's a God. I know there's a God. Sometimes I just can't figure out why God gives and takes away in such quick succession. Why would God begin working a miracle, only to let it end in disaster?
