Titus 1:15 Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled.
Hebrews 13:4 Let marriage be held in honor among all, and let the marriage bed be undefiled; for fornicators and adulterers God will judge. (NAS)
Genesis 1:27-28, 31 So God created man in his own image, in the image of God created he him; male and female created he them. 28 And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth. 31 And God saw every thing that he had made, and, behold, it was very good. And the evening and the morning were the sixth day.
"Sexual activity is 25 percent to 300 percent greater for married couples versus the non-married, depending on age. The good news is that most married couples are doing something right. Not only do married couples have sex more often, but they enjoy it more, both physically and emotionally."
"Sex is the highest form of intimacy two humans can have, which distinguishes marriage from any other natural relationship.”
"Sex is an inherent and integral part of almost every marital relationship. The romantic and sexual attraction between a man and woman has persisted throughout the ages and still continues to be one of the most basic aspects of a person's life. Without it there might not even be such a thing as marriage."
Genesis 2:22-25 And the rib, which the LORD God had taken from man, made he a woman, and brought her unto the man. 23 And Adam said, This is now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man. 24 Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh. 25 And they were both naked, the man and his wife, and were not ashamed.
1 Corinthians 6:16 Or do you not know that he who is joined to [sexual intercourse] a harlot is one body with her? For "the two," He says, "shall become one flesh."
Matthew 19:5 And [Jesus] said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they two shall be one flesh? 6 "So then, they are no longer two but one flesh. Therefore what God has joined together, let not man separate."
"The phrase becoming one flesh sheds considerable light on God’s estimate of sex within a marital relationship. It tells us that God sees sex as a means through which a husband and a wife can achieve a new unity. It is noteworthy that the "one flesh" imagery is never used to describe a child’s relationship to his father and mother. A man must "leave" his father and mother to become "one flesh" with his wife. His relationship to his wife transcends the one to his parents because it consists of a new oneness consummated by the sexual union."
"When you have sex with your spouse you should feel closer to him/her, more like one instead of two. You should feel a deepening of the love shared between the two of you. This is exactly what God wants from husbands and wives, to be in a state of oneness."
Genesis 4:1 And Adam knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man from the LORD.
"Self-disclosure through sexual intercourse invites self-disclosure at all levels of personal existence. This is an exclusive revelation unique to the couple. They know each other as they know no other person. This unique knowledge is tantamount to laying claim to another in genuine belonging . . . the nakedness and physical coupling is symbolic of the fact that nothing is hidden or withheld between them."
"The fact is, God ordained sexual intercourse as a way to foster unity in marriage, which means it has the power to create intense emotional and spiritual bonds between you and your spouse."
"Love making creates tighter bond between the couple and it allows the couple to experience a pure expression of love in their marriage towards one another."
"Recently, researchers detailed how orgasms increase levels of the hormone oxytocin, the so-called love hormone, which helps us bond and build trust. Higher oxytocin has also been linked with a feeling of generosity."
"The sex life of a married couple is usually in some way a reflection or indicator of whatever state the relationship in. Ruling out any physical or medical cause of difficulty, the lack of sex in a marriage is a symptom of the lack of intimacy in a marriage."
"While the marriage relationship does not solely depend on sex in order to be a success, it is difficult to have a successful marriage without it."
“While sex isn’t the only important thing in a marriage, it matters more than many believe. Couples who don’t have satisfying sex lives are more likely to get divorced. Plus, regular, intimate sex can help increase general happiness.” Donnelly adds, “Happy couples have more sex, and the more sex a couple has, the happier they report being.” Sociologist, Denise A.
