It is always heartbreaking when you start to think of all the people in your life who don't know God. How could they possibly understand the love we give when they don't know Him who is Love? Human love is so fickle and frail, but the Love of God- the Love that is Jesus Christ Himself, is the absolutely epitome of perfection. We love because He first loved. True, pure, eternal love is only available through Jesus. He doesn't just show love, HE IS LOVE.
Maybe The Beatles had it right... Love is all you need.
