True love is from God and is based upon who He is; "God is Love." Because He is love, he is the source of all true love.
Now what does that mean? God loves because that is who he is. That is His nature. We are his children. As his children, we take on the character and nature of God: therefore we are love. We love because that is who we are. Also, remember, love is a verb, it is a "being" and "doing" word. Love is who we are and, because of that, love is what we do.
