If misused, it can lead him down to the lowest depths of degradation.
It is indeed, as one has said, Sexual desire is as normal as the desire for food and for rest.
But the God Who created these desires has also ordained the means for their legitimate satisfaction. This is evident from the fact that it was created before man fell into sin and existed in a world which God Himself considered "Very Good".
But ever since the Fall of man, his view of sex has been perverted and he himself has become a slave to sexual desire.
The cinema, the advertising world and much of the cheap literature sold on book-stalls today have all served to give a crooked and perverted conception of that which God intended to be pure, beautiful and holy. Lewis writes, "You can get a large audience together for a strip-tease act - that is, to watch a girl undress on the stage.
There is abundant evidence to prove that our thoughts about sex are perverted. Now suppose you came to a country where you could fill a theatre by simply bringing a covered plate on the stage and then slowly lifting the cover so as to let every one see, just before the light went out, that it contained a mutton chop or a bit of bacon, wouldn't you think that in that country something had gone wrong with the appetite for food?
As a result, sex which was meant to be a blessing to man has become a burden instead.
The word "sex" itself has an impure connotation in the minds of most people today because of man's repeated abuse of this God-given function.
I have also seen many "Christian" marriages that have fulfilled the devil's purpose instead of God's.
I cannot but open fire now with the deadliest weapons in God's armoury.
There is nothing inherently sinful in dynamite, it all depends on how and for what purpose it is used: so with sex.
If accepted as God's gift and used wisely under God's control, it can be the means of man's highest fulfilment.
He must therefore stand against the world's low views of sex, which reduce it to a mere physiological phenomenon and a source of pleasure.
