When we read 1 Corinthians 6:12-20, we see two cultural myths about sex: 1) I can do whatever I want with my body; and 2) Sex is just an appetite. The biblical message that counters the second myth is: Sex is the donation of your full humanity to another. Now let's look at how Paul debunks the first myth.
Sex is not just an appetite, it is the donation of your full humanity to another. Now let’s debunk that first myth: I can do whatever I want with my body. Look back at our passage again. Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought at a price.
As it turns out, when you become a Christian, your body doesn’t belong to you anymore. It belongs to God, and he has turned you into a house where he lives by his Holy Spirit. Your body is not your own. God bought it and moved in.
The implications of this reality are overwhelming, but let me just give you one: If you are a Christian, whenever you do anything, including sex of any kind, God is there. Now that might totally creep you out or freak you out, but understand this about God: God designed sex, but he is not sexual. God is what’s called supersexual, he is beyond sexuality.
You see, all the gods and goddesses of all the other ancient cultures were extremely sexual. They were dripping unhindered sexuality. Then the Israelites come along talking about this god called YHWH, and they never talked about him in sexual terms. He is beyond sexuality, yet he has given us this gift to be enjoyed according to his design, and not however we want. The bottom line is this: Christian, your body is not your own. God bought it with the blood and life of his son, and then he moved in in the person of the Holy Spirit.
