Love

"From love arises hatred of those things which are contrary to what we love, or which we oppose and thwart us in those things that we delight in. It is from the various exercises  of love and hatred, according to the circumstances of the objects of these affections, as present or absent, certain or uncertain, probable or improbable, that arise all those other affections of desire, hope, fear, joy, grief, gratitude, anger, etc."

-Signs Of The Spirit, Jonathan Edwards Quoted, Pg. 49
