The origin of sex and sexual desire is the heart and mind of God. He is the designer. What does that tell us about the nature of sex? That it is by nature (according to its original design) a good thing. However, as great a gift as sex is, it is still not an ultimate thing. There is a transcendent nature to sex, a glory that is meant to turn our gaze upward, to put on display Christ's self-giving devotion to His church.
