It seems to me that when a person is converted to Christianity as an adult, and then becomes a parent, there is a common pitfall they fall into. It is not easy to recognize the real nature of our fallen state, and it is the most natural thing to love our children dearly and want the best for them. So it seems common that this adult convert to Christianity will believe, perhaps even only on an unconscious level, that his children can be spared all the pain and sorrow that he himself experienced from falling into sin, if only he raises their children right. He will simply put in place all the right rules, strict discipline, and thorough indoctrination in the Christian faith, and the result will be that his child will have a relatively trouble-free life, without falling into any of the gross and destructive sins which he himself experienced. Or even more simply, he will simply shelter his child from anything that might corrupt him, and expect him to turn out fine. Any parent can be tempted with this, of course, but it seems like it’s a particular temptation for the first generation Christian parent, who perhaps doesn’t realize that he would still have been a sinner, a bad sinner, even if he grew up in a Christian home.
