1 Thessalonians 4:3-8

Twentieth_Century(i) 3 For this is God's purpose--that you should be pure; abstaining from all immorality; 4 Each of you recognizing the duty of taking one woman for his wife, purely and honorably, 5 And not for the mere gratification of his passions, like the Gentiles who know nothing of God; 6 None of you over-reaching or taking advantage of his Brother in such matters. 'The Lord takes vengeance' upon all who do such things, as we have already warned you and solemnly declared. 7 For God's Call to us does not permit of an impure life, but demands purity. 8 Therefore he who disregards this warning disregards, not man, but God who gives you his Holy Spirit.
