1 Thessalonians 4:3-12 NASB1995
For this is the will of God, your sanctification; that is, that you abstain from sexual immorality; that each of you know how to possess his own vessel in sanctification and honor, not in lustful passion, like the Gentiles who do not know God; and that no man transgress and defraud his brother in the matter because the Lord is the avenger in all these things, just as we also told you before and solemnly warned you. For God has not called us for the purpose of impurity, but in sanctification. So, he who rejects this is not rejecting man but the God who gives His Holy Spirit to you.
Now as to the love of the brethren, you have no need for anyone to write to you, for you yourselves are taught by God to love one another; for indeed you do practice it toward all the brethren who are in all Macedonia. But we urge you, brethren, to excel still more, and to make it your ambition to lead a quiet life and attend to your own business and work with your hands, just as we commanded you, so that you will behave properly toward outsiders and not be in any need.
