I'd like to break this down for you as I see it and hopefully it will help you find ways to understand it yourself.  We have all learned about the atomic structure of the earth.  That everything is made up of a collection of atoms pressed together to form an object.  Even our bodies are made up of cells that are constantly being replaced in like manner.  Atoms are the base structure of all that is manifest in our world.  

How does this relate to love you ask.  Most folks think of love as an emotion.  Emotion is -  energy in motion, much like the atoms bouncing around in the air right now.  Energy that we focus through our thoughts projected towards something.  This energy that we harness and focus is generated by the source of all life which is commonly known as God.  

God - Allah - Jehovah - or the Eternal Flame is that which creates and sustains all things is the life force or energy in back of all.  Now that is love!  The unconditional projection of It's life as our life.  This energy can be used either for love which uplifts and expands or for fear which constricts. 

This is probably a very complex answer for a simple question but with this answer I am trying to explain how we confuse love with fear.
