4 Let marriage be kept honorable in every way, and the marriage bed undefiled. For God will judge those who commit sexual sins, especially those who commit adultery.
18 Keep on running away from sexual immorality. Any other sin that a person commits is outside his body, but the person who sins sexually sins against his own body.
19 You know that your body is a sanctuary of the Holy Spirit who is in you, whom you have received from God, don't you? You do not belong to yourselves,
29 to keep away from food sacrificed to idols, from blood, from anything strangled, and from sexual immorality. If you avoid these things, you will prosper. Goodbye."
1 Now concerning the things you wrote about: It's good for a man not to touch a woman.
2 But because sexual immorality is so rampant, every man should have his own wife, and every woman should have her own husband.
5 For you know very well that no immoral or impure person, or anyone who is greedy (that is, an idolater), has an inheritance in the kingdom of Christ and of God.
