This song is about finding comfort and companionship when feeling lonely or tired from life's travels. The lyrics describe how even when one forgets to believe in their heart, a loved one can still call out and open the door to their heart, bringing tears of comfort. The chorus reinforces that love is always nearby to call out to as a friend of the heart during weary times.
