1 Corinthians 6:19-20 (ESV)
19 Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, 20 for you were bought with a price. So glorify God in your body.
We live in a culture in which people believe that privacy and personal rights are everything. We assume, because it has been handed to us by others, that we have full right to personal autonomy. We are taught to be true to ourselves above all things. Sure, we are taught to be good to others and that to harm others is wrong, but we are also taught that, when it comes to ourselves, we are the masters of our own ships, the captains of our own souls.
Contrast the view that we are handed by the world with the declaration of Scripture, and you will see why, to some people, Christianity is so very strange. One truth of being a believer is the fact that, in Christ, we are not our own. This is not to say that we lose all concept of personality. Rather it is to say that, in our relationship with God we are servants to a Master, children under the authority of a Father. Or, in this passage, redeemed slaves, purchased to serve a perfect Lord.
Before we turn up our noses at the sacrifice of such human freedom, let us remember that God has created us in his image and for his glory. He has designed us in such a way that to serve and honor him is the source of ultimate happiness. When we obey God and show the world around us his greatness, we do the thing for which we exist. Nothing can truly satisfy our souls like doing the thing for which we were created. Thus, being a servant to the Master is joy, not begrudged duty.
Remember, believers, that we are not our own. Freedom is not the ultimate to the Christian. Yes, we love political freedom, freedom to worship God without government control or restriction. However, we dare not think that we are free to dishonor God in our lives. God has not granted us that freedom. God has called us to serve him, to obey him, to be his. He bought us at a price. We are his. We owe him glory. And, the best news of all, when we give him that glory, he grants joy to our souls, because our souls are then doing the very thing for which they exist.
