3It is God’s will that you should be sanctified: that you should avoid sexual immorality; 4that each of you should learn to control your own body Or learn to live with your own wife; or learn to acquire a wife in a way that is holy and honorable, 5not in passionate lust like the pagans, who do not know God; 6and that in this matter no one should wrong or take advantage of a brother or sister. The Greek word for brother or sister (adelphos) refers here to a believer, whether man or woman, as part of God’s family. The Lord will punish all those who commit such sins, as we told you and warned you before.
