The world and the Devil are quick to teach them in their own way what the Church should have taught them first in a pure way.
Ignorance about the Scriptural teaching on these subjects has left most young people defenceless against Satan's subtle attacks in these realms. It presents sex, love and marriage from God's viewpoint.
In every man and woman there exist sex instincts and wants.
These instincts may not be of the same strength in all, but they do constitute a powerful force in all normal human beings for at least thirty years after adolescence.
I would urge young people to read through this book seriously. In many places where I have used the pronouns, "he" and "him", they do not refer only to men.
