Today we read 1 Thessalonians 4:1-10 in our reading plan. Here is some help from John Piper, in a sermon on 1 Thessalonians 4, “This is the Will of God For You: That You Abstain From Sexual Immorality”
Start reading with me at [1Thessalonians 4] verse 4: “That each of you know how to possess his own vessel in sanctification and honor, 5 not in lustful passion, like the Gentiles who do not know God.” There it is: “like the gentiles who do not know God.” When you give way to lustful passion, you act like people “who do not know God.” Which means: knowing God is the path to sexual purity. If you are struggling with sexual impurity in mind or body, the immediate and long term strategy is know God, know God!
Be careful here! Don’t nullify 1 Thessalonians 4:5 by saying with a cynical tone: “Good grief, there are world-class theologians who are in bondage to lust and who leave their wives. So what good is all this knowledge about God?” Indeed there are. And I say with tremendous confidence: they don’t know God. To know ten thousand facts about God is not to know God.
Knowing God is the path to sexual purity. And if you are in bondage to pornography and fantasies or fornication or adultery the immediate and long-term strategy of this war is: Know God! Know God! Lustful passion is the mark of the Gentiles who do not know God. (See 1 Peter 1:14; Ephesians 4:22; Romans 1:23-28.)
…….Knowing God is the path to sexual purity because the purpose of sex and the purpose of the body is to magnify the supreme worth of God and the infinite value of Jesus Christ. And he will not be seen as supremely worthy and infinitely valuable if knowing him is not the key and the path of our liberation. “You will know the truth and the truth will set you free” (John 8:32). And Jesus said, “I am the way the truth and the life” (John 14:6). Knowing God, knowing Christ, is the path to sexual purity.
Knowing God through His Word ... Day by Day
