A few days ago we considered how to pursue purity. Today, we want to consider why we should pursue purity. I Corinthians 6 gives us several reasons:

First, those who practice sexually immorality will not inherit the kingdom of God (v9-10). These words ought to startle us awake. Living in sexual sin is simply incompatible to a relationship with the Lord. Those who are living together, sleeping around, or practicing homosexual acts have no reason to think they are saved – they are outside the kingdom of God.

Second, sexual immorality belongs to our old way of life (v11). “Such were some of you,” but not anymore. Now we have been washed from that dirty behavior. Now we have been set apart from those sins. Now we are declared righteous in Jesus. We have a new life, and sexual immorality can have no part in it. In other words, we must live out who we now are in Christ.

Third, our bodies are meant for the Lord (v13-18). We are to use our bodies in service to Jesus, not in service to sin. How could we join our bodies to another in sexual sin, when we are joined to Christ?

Fourth, our bodies are temples of the Holy Spirit (v19). How could we desecrate his temple by involving it in sexual sin? God is holy, and as his temples, we must strive to be holy.

Fifth, our bodies belong to God (v19-20). When Jesus died to pay for our sins, he purchased us out of our slavery to sin. We now belong to him. And so we must use our bodies to glorify him. Our actions must honor him.

Sexual immorality of all kinds is a characteristic of the old sinful way of life that is destined for hell. But in Christ, we have been washed and justified; we have a new life. Our bodies are set apart unto God. They are meant for the Lord. They are temples of the Holy Spirit. They belong to Him.

And so we must flee sexual immorality.
