I think it is so easy sometimes to present a plan to God and ask him to make it happen, we can sometimes convince ourselves that we've thought of a brilliant way to serve God. God will use us however he wishes and it's quite a big step to say to God I am ready for you to use me in whatever way you want as it is completely out of our comfort zone. We don't realise that God is the one that knows what is best for us, he has his plan ready to work out that will be so much greater than we could ever imagine.
It's a question you get asked so much when you say what degree you're doing; 'what do you want to do with your degree?' and you feel pressured into saying something rather than nothing. At the moment I really feel that God's calling me to teach, I can't imagine doing anything else really but who knows! It can be scary to say to God I surrender my life to you and not know what's ahead, the unknown is generally quite scary! It's difficult to remember sometimes that even the things you feel like you've just got to get out of the way in order to do something else, are part of God's plan and are for his glory. I'm saying all this but I know there are times when I don't surrender a situation to God in prayer or I think that something's too small to bother God with. The amazing thing is that even those things you think will not matter to such a powerful, holy, transcendent God are so important to him, he wants us to commit them to him, and he will sort them out for the good!
