The bible is clear. It says that sex should be restricted to married people only. The Bible views the body as important - something to be taken care of and be not used as a sexual toy.
Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, 10 nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. And such were some of you. But you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God. 1 Corinthians 6:9-11 (NKJV)
Foods for the stomach and the stomach for foods, but God will destroy both it and them. Now the body is not for sexual immorality but for the Lord, and the Lord for the body. 1 Corinthians 6:13 (NKJV)
Do you not know that your bodies are members of Christ? Shall I then take the members of Christ and make them members of a harlot? Certainly not! Or do you not know that he who is joined to a harlot is one body with her? For "the two," He says, "shall become one flesh." But he who is joined to the Lord is one spirit with Him. Flee sexual immorality. Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body. Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God, and you are not your own? For you were bought at a price; therefore glorify God in your body and in your spirit, which are God's. 1 Corinthians 6:15-20 (NKJV)
Now concerning the things of which you wrote to me: It is good for a man not to touch a woman. 1 Corinthians 7:1 (NKJV)
But I say to the unmarried and to the widows: It is good for them if they remain even as I am; but if they cannot exercise self-control, let them marry. For it is better to marry than to burn with passion. 1 Corinthians 7:8-9 (NKJV)
Nevertheless he who stands steadfast in his heart, having no necessity, but has power over his own will, and has so determined in his heart that he will keep his virgin, does well. 1 Corinthians 7:37 (NKJV)
No temptation has overtaken you except such as is common to man; but God is faithful, who will not allow you to be tempted beyond what you are able, but with the temptation will also make the way of escape, that you may be able to bear it. 1 Corinthians 10:13 (NKJV)
Marriage is honorable among all, and the bed undefiled; but fornicators and adulterers God will judge. Hebrews 13:4 (NKJV)
For in that He Himself has suffered, being tempted, He is able to aid those who are tempted. Hebrews 2:18 (NKJV)
For we do not have a High Priest who cannot sympathize with our weaknesses, but was in all points tempted as we are, yet without sin. Let us therefore come boldly to the throne of grace, that we may obtain mercy and find grace to help in time of need. Hebrews 4:15-16 (NKJV)
Now the works of the flesh are evident, which are: adultery, fornication, uncleanness, lewdness, idolatry, sorcery, hatred, contentions, jealousies, outbursts of wrath, selfish ambitions, dissensions, heresies, envy, murders, drunkenness, revelries, and the like; of which I tell you beforehand, just as I also told you in time past, that those who practice such things will not inherit the kingdom of God. Galatians 5:19-21 (NKJV)
Blessed is the man who endures temptation; for when he has been approved, he will receive the crown of life which the Lord has promised to those who love Him. James 1:12 (NKJV)
then the Lord knows how to deliver the godly out of temptations and to reserve the unjust under punishment for the day of judgment, 2 Peter 2:9 (NKJV)
But fornication and all uncleanness or covetousness, let it not even be named among you, as is fitting for saints; neither filthiness, nor foolish talking, nor coarse jesting, which are not fitting, but rather giving of thanks. For this you know, that no fornicator, unclean person, nor covetous man, who is an idolater, has any inheritance in the kingdom of Christ and God. Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience. Therefore do not be partakers with them. Walk in Light For you were once darkness, but now you are light in the Lord. Walk as children of light Ephesians 5:3-8 (NKJV)
And have no fellowship with the unfruitful works of darkness, but rather expose them. For it is shameful even to speak of those things which are done by them in secret. But all things that are exposed are made manifest by the light, for whatever makes manifest is light. Therefore He says: "Awake, you who sleep, Arise from the dead, And Christ will give you light." Ephesians 5:11-14 (NKJV)
