Why did God create sex and yet it would seem that He has placed so many stipulations around it? Joshua Harris attempts to succinctly answer that question in the above video clip from The Gospel Coalition. In short, I think the answer if found in the simple fact that all of life does not revolve around us. If we really believe that God created us, then it would follow that there is a creation/creator relationship that we must take seriously as Christians.
As creator, God thought up sex. He created it and He created it good. Because God designed sex, it is meant to be enjoyed as He has designed it. No doubt there are myriad abuses of God’s design for sex in our world today and I think each of these abuses can be traced to a failure to recognize God’s design in sex. In short, our culture’s view of sex is very selfish. One night stands, pornography, and even homosexuality (on some level) hinge on the idea that sex exists primarily for our own gratification (i.e. the idea that if you have an inward desire, surely it must be filled–when we do that we are making ourselves ultimate rather than God)–these things are inherently selfish. If, however, we believe that God is creator and is ultimate and He created us in His image, then it follows that sex exists not primarily for our personal self-fulfillment but rather as a means of glorifying God. When a man and a woman enjoy sex within the confines of marriage, God is honored because we express love for Him by honoring His design and we experience satisfying joy in Him because we recognize sex as what it really is–a gift from God.
As creatures made in God’s image, we enjoy His gifts most when we submit to His design–its no suprize that when we neglect to honor His design, despair ensues. God is supremely satisfied in himself and we will only find true and lasting satisfaction in God Himself . . . this reality ought to transform the way we think about everything, including sex.
