Just so all of you can read this I put it in "Thought" form instead of just remark.No, I think that God doesn't have someone picked out for us. Or the perfect one in mind. When Amber and Aaron were doing their premarital marriage counseling their Christian counselor told them that every 5 years they would find someone more compatible with themselves then their spouse and another 5 years someone even more compatible. So if God had someone in mind wouldn't it be the one that was absolutely compatible? I also know many Christian families fall apart because of divorce even when they prayed for the right person time and time again. I believe that God does have a will for us, but I do not believe that he says "You, Austin, will marry so and so in the month of July." no that is silly to say you have free will but God says that you will do this and  you have to do that or that you have to marry her. He even gives you a choice to obey his will or not. It is indeed his will that you go to church, whether you do that or not is your choice. It is also his will that you read your Bible once again your choice.Now bare with me this all relates back. So ok, when it comes to bigger things such as large scale ministry work, I think that you still have a choice but it will get done whether you let God use you or not. Say that you know God put going to Brazil to do ministry work on your hear, and you don't go. He will get someone else to because it will get done. Not much longer I promise I will get relate this back. So if God lets you make those kind of choices I also believe that God can use you no matter what, where, how, and when. That means that if you are praying "God should I move to NC and start a church or should I start one here?" I would say that he would answer it, but I believe that he would probably answer it "You make the choice that is best for your family" Because no matter where you are God Can Use You! Now it is not to say that he doesn't care because he does. He cares so much that he knows every hair on your head. So if he can use you no matter what concerning something as big as ministry then I am sure he can use you no matter what concerning marriage. Now, if he can use you no matter what or when doesn't that mean that he can teach you something where ever you are? So, in that theory I believe that where ever you are that probably means that you are supposed to be there in that moment. Now if you are at a dead point in your relationship with Christ you can be taught something but you should work to remove your self from that stalled period  in your life.
