I was telling Robert the other day that it is so hard to know exactly what it is that God wants you to do, but you still have to wait. But, I have finally come to a place in my life in which I know in my heart (not just my head) that God is in control and he has everything planned. I came across this entry in "My Utmost for His Highest" today (it's for tomorrow hehe), and it was perfect.
"There are times that you can't understand why you cannot do what you want to do. When God brings a time of waiting, and appears to be unresponsive, don't fill it with busyness, just wait. The time of waiting may come to teach you the meaning of sanctification- to be set apart from sin and made holy- or it may come after the process of sanctification has begun to teach you what service means. Never run before God gives you His direction. If you have the slightest doubt, then He is not guiding. Whenever there is doubt- wait.At first you may see clearly what God's will is- the severance of a friendship, the breaking off of a business relationship, or something else you feel is distinctly God's will for you to do. But never act on the impulse of that feeling. If you do, you will cause difficult situations to arise which will take years to untangle. Wait for God's timing and He will do it without any heartache or disappointment. When it is a question of the providential will of God, wait for God to move."
There's more, but this says it all to me :).
