That statement will undoubtedly be maligned, criticized, and considered incredibly naive by a great many (if not most) of the people in our permissive contemporary society. But, it is true nonetheless. There is definitely a pleasurable, recreational aspect to sex that was expressly put there by God for the enjoyment and delight of His creatures. But, the fact remains that its primary purpose is to create life.
I write this because our society has focused for far too long on promoting sex outside of marriage as normative behavior to be engaged in casually by anyone older than about twelve.
We look at teen pregnancies, sexual abuse, Sexually Transmitted Diseases, pornography, and abhorrent sexual behaviors as grave societal problems, which they certainly are. But these problems have not arisen because we don't use condoms, or aren't careful when engaging in sex, or don't have the right filters on our computers, or don't properly enforce the laws that are already on the books.
They have grown to overwhelming proportions because we have totally missed the point that sex is NOT primarily a recreational activity. Sex produces babies. It was designed to do just that.
Several cultures in the ancient world practiced infant sacrifice. This occurred in part because their rampantly immoral lifestyles and worship practices resulted in unwanted babies. What do you do to get rid of unwanted babies? Offer them to your "gods!" We do something similar with the unwanted babies that have resulted from lifestyle choices in our culture. We call it abortion.
Do you know the real difference between infanticide and abortion? In abortion, you don't hear them scream.
