Overprotection

I am not a father, so if you want to hear the opinion from someone with firsthand experience, then just ignore me. I have secondhand experience, though, and it may have given me better insight than firsthand experience can.
Most parents seek to find a way to protect their child from evil and raise them in a way that would, frankly, make them good. I believe that there is a point on both sides that goes too far. All things in moderation, no? A child should be protected from the evils of this world, but there is a point where he or she should be shown the world outside of a bubble. Otherwise the child will not mature, a problem that I have seen in more than one instance. If the child is to act his age, then he must be shown the world around him, from all aspects. He cannot be hidden from evil forever. He must be taught and then shown the two paths, not hidden from the choice. After all, childlike faith is encouraged by the Bible, but not childlike maturity. We are to mature, but keep faith in or Lord. We cannot remain children in all aspects in this world. Nor can we hide in the past, raise our children the same way our parents did. Times change, and parenting must change with it. The foundations should never change, but the specifics are already changing with every generation. We cannot pretend that the past was so much better, and teach our children to live as if everything was the same. A child must be exposed to the present if he is to survive in it.
In writing this I do not intend to criticize, but to share my own thoughts.
