Commentaries:
The picture here is of a slave being purchased from the horrible system of slavery. Redemption implies the buying back of something or the paying of a ransom. Paul's illustration is that we have been bought from slavery to sin. Up to the point of redemption, our lives have been the lives of slaves.
What we have received is the most expensive gift that has ever been given to purchase mere slaves. We have been bought with a price—the very life of the Creator. Paul is undoubtedly using this illustration to emphasize to us that, because we have been purchased, we are under obligation to the One who purchased us. As he writes, "Therefore glorify God in your body and in your spirit, which are God's." In other words, he is imploring us to become holy. This is our moral responsibility as purchased slaves.

The Awesome Cost of Salvation
Adultery creates a second one-body/one-flesh bond in opposition to the marriage. This will inflict severe damage upon the marriage relationship. The apostle says such sexual sins hurt so much because they are "sins against [our] own body" (verse 18).
Paul comes to his primary point in verses 19-20: We are not our own! God bought us at an incredibly high cost, the blood of our Master, and thus He commands us to "glorify God in your body and in your spirit," both of which are His! God owns us completely!
The import of this is staggering! When we commit sex sins—even in our minds—we have first become unfaithful to God! When we break the seventh commandment, we show infidelity to God! Yes, it shows infidelity to the wronged spouse, but it all beginswith unfaithfulness to God.
The road to adultery starts when we become willing to break the vows we made to God at our baptism. We promised then that we would honor and obey Him exclusively and faithfully, accepting Him as our Savior, Master, and soon-coming King and Husband. When we are willing to walk away from the commands He gives us about sex and marriage, we begin to walk into the arms of adultery. Physical adultery starts with spiritual adultery!
If an adulterer desires to repent, he must first acknowledge that he has sinned against God. King David, in his moving prayer of repentance after the murder of Uriah and adultery with Bathsheba, cries out, "Against You, You only, have I sinned, and done this evil in Your sight" (Psalm 51:4). Did he not also sin against Uriah, Bathsheba, the nation, his wives, and his children? Of course! But ultimately, his sin was against God! When we are faithful to God and our covenant with Him, we will not commit sex sins.

Sex, Sin and Marriage
Upon acceptance of the blood of Jesus Christ for the forgiveness of sin, we become His since He bought and paid for us by His death. As His possession or servant (literally "slave"), He expressly forbids us to engage in any sexual immorality. In addition, the spirit of God's law helps us to understand fornication as unfaithfulness against one's future mate. Virginity should be held in reserve for the one we eventually marry, so he or she will not receive a mate defiled by intimacy with somebody else.
And, just as with adultery, though God forgives a fornicator of his sin, the effects of fornication will take their toll. God's law produces a penalty automatically. Sometimes it manifests itself in disease. Other times may see a child born out of wedlock or a "shotgun" marriage of two incompatible people. A few minutes of forbidden pleasure is not worth the price!
Paul writes to the Thessalonians:
For this is the will of God, your sanctification: that you should abstain from sexual immorality; that each of you should know how to possess his own vessel in sanctification and honor, not in passion of lust, like the Gentiles, who do not know God; that no one should take advantage of and defraud his brother in this matter, because the Lord is the avenger of all such, as we also forewarned you and testified. For God did not call us to uncleanness, but in holiness. (I Thessalonians 4:3-7)

The Seventh Commandment (1997)
The basis for our obligation to Christ could not be stated any clearer. He gives three reasons:
1. Verses 9-11 show what put us into indebtedness to make redemption necessary.
2. Verse 19 says that our body is now the temple of the Holy Spirit.
3. Verse 20 states that, because of redemption, we now belong to the One who redeemed us, and we must glorify Him in body and spirit.
Concerning our bodies being "the temple of the Holy Spirit," it is good to reflect on the Old Testament symbolism that God abode in the Holy of Holies within the Temple. Paul reminds us that God now lives in us (John 14:17, 23), and we are obligated to live with the utmost circumspection so that He in no way is defiled by our conduct. So it is with Christ: We are obligated to consider His demands in every area of life all the time and under every circumstance. What an honor!
