Think what you're saying.

Watching a T.V. comedy the other night, I heard one of the characters say, "It's just sex!" I'm thinking, did you know what you just said? How about saying "It's just a tsunami!"
They don't seem to get it. Sex is how new people get brought into the world. People forget that and treat it like recreation, of no big consequence at all. But that is what cause new life and every time a new baby is born, history changes. They might never be famous, or recorded in history,or have a wide impact on others, but the human race has changed, because one more being created in the image of God has come into it; and sometimes things will be shaken up in a big way.
That could be good or bad. Adolf Hitler, Josef Stalin and Jack the Ripper, whoever he was, each made a big impact - not a good one. Mother Theresa, Florence Nightingale, Abraham Lincoln and WIlliam Wilberforce each made a big impact - a very good one. And it started when two humans engaged in intimate contact and a new life was conceived. Hardly a small thing.
Jesus once said that you don't take the childrens' bread and throw it to the dogs. There is a certain respect due to certain things. The importance of them needs to be properly remembered and appreciated. You are changing history when you cause the birth of a child, whether the fact is widely remembered or not. The momentous life ever lived on Earth, interestingly, is an exception: Jesus Christ was born of a virgin woman and no human sexual contact was involved. People try and call that an unimportant detail, but it's actually a very important one. It shows the unique and miraculous nature of Jesus. Any other human being was born because of that contact between a a man and a woman, and we'd do well to think what we're doing.
Of course some people find ways of separating sex from birth. A married loving relationship may well involve physical intimacy without wanting to have a child every year, too, but who dares stop a life once started from running its intended course?
Think what you're saying, characters and scriptwriters. "Just sex" is like saying "Just an earthquake". Sex causes birth, and once a person is born the world has changed. It may be a huge blessing, too. That depends on whether or not it is given to God properly. Some people just don't know what they're messing with! We all need to think what we're saying.
