1 Thessalonians 4:7 For God did not call us to be impure, but to live a holy life.
Paul instructs the Thessalonians about living to please God. There are three things he speaks to them about. 1) It is God's will that you should be sanctified: that you should avoid sexual immorality, that each of you should learn to control his own body in a way that is holy and honorable, not in passionate lust like the heathen, who do not know God. . . 2) Now about brotherly love we do not need to write to you, for you yourselves have been taught by God to love each other. 3) Make it your ambition to lead a quiet life, to mind your own business and to work with your hands, just as we told you, so that your daily life may win the respect of outsiders and so that you will not be dependent on anybody.
The way that we live is important to God. He came to set us free from those things that are impure so that we might experience His full blessings and not be bogged down with things that would keep us from Him and the fullness of all that He has created us for. And we are called to be His witnesses in this world. We are to re-present Him. We are His children. That is who we are. We are made in His likeness. And how can we live in Him and walk in His likeness? We have been given His Spirit. Galatians 5 tells us, So I say, live by the Spirit, and you will not gratify the desires of the sinful nature. . . But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control . . . Those who belong to Christ Jesus have crucified the sinful nature with its passions and desires. Since we live by the Spirit, let us keep in step with the Spirit. Keep stepping toward the blessed life.
God calls us upward. And if we have stepped aside, His grace is there to bring us back onto the path again. For the grace of God that brings salvation has appeared to all men. It teaches us to say "No" to ungodliness and worldly passions, and to live self-controlled lives in this present age, while we wait for the blessed hope--the glorious appearing of our great God and Savior, Jesus Christ, who gave himself for us to redeem us from all wickedness and to purify for himself a people that are his very own, eager to do what is good (Titus 2:11-14).
