What is Love anyway?

In the text book we learned about the different kinds of love: agape (unconditional), storge (between parents and children, eros (passion), and philia (friendship). So what is love when there are so many different apects and combinations of it. M. Scott Peck said, "I define love thus: the will to extend one's self for the purpose of nurturing one's own or another's spiritual growth."  I agree with Peck's answer, however I think it can apply to other aspects of an indivdiaul such as emotional, intellecutal, personal growth. We can also look to our Heavenly Father and Savior Jesus Christ as perfect examples of love. According to the Bible dictionary, Charity is the highest, noblest, strongest kind of love, not merely affection. It is the pure love of Christ. I think that this kind of love relates well with agape in that it is unconditional and that one doesn't expect anything in return.  When we are exhorted to pray for charity in the scriptures I think this is the kind of love that God wants us to develop for ourself and others.
