And he answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female, And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh? Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.  Matthew 19:4-6.

For this is the will of God, even your sanctification, that ye should abstain from fornication: That every one of you should know how to possess his vessel in sanctification and honour; not in the lust of concupiscence...
I Thessalonians 4:3

And Jesus knowing their thoughts said, Wherefore think ye evil in your hearts? Matthew 9:4

Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ;  II Corinthians 10:5

Neither shalt thou lie with any beast to defile thyself therewith: neither shall any woman stand before a beast to lie down thereto: it is confusion. Leviticus 18:23

Contrary to popular opinion, the Christian lifestyle of purity and abstaining from premarital .and extramarital sex is not repressive or legalistic. People who have adopted this standard of purity can testify to the liberating power that it has had in their lives. Sexual purity not only is a defense against sexually transmitted diseases such as AIDS, but it also can help to bring about stable and happy marriage and family relationships.

In hoping to live our lives according to Biblical standards and obtain the happy benefits of this lifestyle, we must keep pure by fleeing immorality and thinking on those things which are pure.

Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body. What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and  ye are not your own? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's. I Corinthians 6:18-20 .

FORNICATION
1. The incontinence or lewdness of unmarried persons, male or female; also, the physical union of a married man with an unmarried woman.
2. Adultery. Matthew 5
3. Incest. I Corinthians 5
4. Idolatry; a forsaking of the true God, and worshipping of idols. II Chronicles 21, Revelation 19.

1.  Degradation of women
Women and their skin are being used to advertise every product, cosmetic, dress, perfume and even medication. It is a form of oppression of women and a form of enslaving them. Many of the exercise videos are using obscene positions to see those programs. Many of the unnatural sex acts shown in some of the X-rated movies are committed by force and under threat.  Many of the tortures which are shown in bondage are against the will of women.

2. Watching nudity desensitizes men and women to normal sexual stimulus.
People get used to it and therefore this is the most common cause of psychological impotency in this country.  Just by becoming used to these in order to get an arousal, they have to perform some more weird acts than simple private nudity can provide.

3. Nudity and pornography are an addiction.
This addiction leads to other crimes including drugs, murder, rape, abduction, child molestation and incest. One thing leads to another until a person pays for that crime behind bars for many years to come.  It is not as innocuous as people claim. It is a perversion. There are clubs of sex alcoholics just like Alcoholics Anonymous where people share their previous experiences in order to enter therapy.

4. Finally, it is a waste of time.
The time that is spent on vain desires and pursuit of happiness at the cost of others can be utilized in many constructive ways to include improving their knowledge by reading good books, doing housework, sports, exercise and especially our remembrance of God because to Him is our return.
