The greatest gift that you can give or get is love. True love can't be earned, only given to the undeserving. It has no expectations, and no limits. It gives without bounds and seeks out others before self. It looks on the good, noble and just things, and forgives and guides the areas that falls short of those standards. Maybe this is why the Bible says love never fails, because it continues to see the potential of mankind, and refuses to abandon hope that one day it will realize that full potential.
I honestly believe that love is the highest potential that man can wish to obtain. To love others without preconceived conditions, labels, standards, is difficult, if not downright impossible at times, but that is what real love is. It loves in spite of what a person is, does, or how difficult a situation. I think it takes a stubborn persistence to do this, but real love is putting others first, even when you don't feel like it or when the other person does not deserve it. Love that is earned or deserved is not love, because love is a gift. Love is the ultimate investment, because you invest your heart and soul into another without promise of any return.
I believe that true love is the ultimate revelation of who God is. When I look at my marriage to my dear husband, I see a man who loves me regardless of my mood, looks, what I do. He just loves. There is no way that I could ever earn that kind of unselfish giving of himself, yet he demonstrates that love in words, actions, and his attitude to me. There is a grand security in that fact, because his love is not dependent upon my actions and being earned, I have a security in that love. I have security because it has proven itself to me day after day for going on 6 years (4 1/2 years of marriage and a year and a half of dating), and remains unwavering. And as a gift, it is mine to accept or reject--Love is totally dependent upon me to accept it, but that is all I have to do.
I think God created love in this manner, because he knew love was not something we could ever earn this side of Heaven, and also because He knew that we needed something to bring about a feeling of stability and security in this life. There is nothing more secure that having the love and acceptance of another, and being able to live out your life as you are without having to live as another person deems you should live. I am not saying that we should not hold ourselves to certain standards, or that there is not some standard of morality--I am saying that love does not hold those things over your head as a prerequisite for being the recipient of love.
Love takes us warts and all, and if we allow, transforms us into better people, and in doing so makes us more loving to others. My prayer for you is that your cup overflow with love, so much so that it can't help but spill out to everyone around you!
