How do you know if fear is at work in you? By seeing if you have hope. Hope is a byproduct of fear, wherever there is hope - there is fear. Hope gives fear away and make us realize we fear.
When there is no hope, there is no fear, there is certainty - that which we call intuition, the gut feeling of certainty, the knowing - but which is in fact not intuition but our choice, an allowance to receive that preferable outcome which we are capable of creating. hope not, but know.
