1 Thessalonians 4:3-8

³ It is God’s will that you should be sanctified: that you should avoid sexual immorality; ⁴ that each of you should learn to control your own body^[a] in a way that is holy and honorable, ⁵ not in passionate lust like the pagans, who do not know God; ⁶ and that in this matter no one should wrong or take advantage of a brother or sister.^[b] The Lord will punish all those who commit such sins, as we told you and warned you before. ⁷ For God did not call us to be impure, but to live a holy life. ⁸ Therefore, anyone who rejects this instruction does not reject a human being but God, the very God who gives you his Holy Spirit.
