Love is the expression of one's values, the greatest reward you can earn for the moral qualities you have achieved in your character and person, the emotional price paid by one man for the joy he receives from the virtues of another.

Before the reward there must be labor. You plant before you harvest. You sow in tears before you reap joy.

The Lord recompense thy work, and a full reward be given thee of the Lord God of Israel, under whose wings thou art come to trust. (Ruth 2:12)
