Love is never exclusive. Love is given to a spouse, to a parent, to a child, to a friend, to a co-worker, to a stranger. Love is given to God. Love is given to oneself. It's never dependent upon a particular object.
Love is only love if it is given to all beings.
It's a power that radiates in every direction. Just as the sun gives it's heat and light to everything on this planet, love shines upon all that it encounters. That love must extend to all is the great lesson of the biblical book of Jonah. On Yom Kippur we'll read the story of how God tells the Israelite prophet Jonah to go to the land of Nineveh to pronounce God's judgment upon the people there for their wicked behavior. Now, it's important to keep in mind that the people of Nineveh were the bitter enemy of the Jewish people during Jonah's day.
