Do you know that God loves you?

My dad asked me the other day; what is the most important question you can ask? My answer was; "do you know that God loves you?" if you do, what consequenses does it have for your life? Remember that it's a big difference to know something with your mind, and to know it with your heart. I believe that the longest journey we take in life is the journey from the head to the heart... But the only ticket you need is willingness.
