God's will for each believer is to be made more like the Lord Jesus through His work of sanctification. To that end, we are to abstain from sexual immorality and to use our bodies for the glory of God. How does the Scripture define sexual immorality? What does it mean for the believer to live a life of pure devotion to God? We see these truths over the course of 1 Thessalonians 4:3-8. Here we see both the call to abstain from sinful distortions of God's design and the goodness of His design in the covenant of marriage between one man and one woman united for life to His glory.
