It is the question: How do I know what God wants?
That is always the question. But there needs to be an examination of the "attitude" behind it. What do we assume he is thinking? Is it a guessing game? "He has a will for me, but he's hiding it." Is it punishment-backed? "If I don't get this right, he's going to be mad at me?" What do we feel about the discernment? Anxiety?
So often we forget (in our gut) that the God who has a call is a Father who loves. He wants us to be happy. He has our best interests in mind. Everything in his call is going to be for our eternal joy, his greater glory, and the salvation of multitudes.
So why do we have this fear?
Let us desire the great things, the beautiful things, the true things. Let us give him a heart courageous. And then simply ask: "What is it that you plan for me?" I can bet he will give the answer.
