You want to be receptive to God so that you may see clearly what he wishes you to do for his glory. If there are other things you want to do on your own, you should also clear them with him to see that doing them is also for his glory. This is the harder part. It means you must abandon yourself totally to the Lord. But if you can do that, you'll experience immense freedom and peace and know that you've done the right thing. Again, this is how God has made us.
