God's Love is a one-sided Love because it doesn't have to be returned to be kept alive. God's Love is a freeing Love because it not only frees the one loving from expectations and presumptions, but it also frees the one being loved to respond from his heart and not his defenses. And finally, God's Love is an other-centered Love because it always puts the other person's interests above its own. Natural love, on the other hand, is completely opposite. Natural love is, first of all, a conditional love because it's based upon what we think and feel, what our circumstances are, and how that other person responds to us.
Natural love is also a two-sided love, because it has to be returned in order to be kept alive.
Natural love is also a bondage love because it causes the one loving to have expectations and presumptions, and it causes the one being loved to respond from his defenses and not his heart. And finally, natural love is a self-centered love because it always puts its own interests above others. To me, that says it all. Do a laboratory experiment on yourself and see if you can tell which kind of love you are functioning on. Because, even as Christians, we go back and forth depending upon whether our heart is cleansed or not.
