Hagelin: Before I answer that I want everybody to know that in the back of Home Invasion I have about 38 pages of resources -- real help -- so you don't have to go it alone. There are people who believe like you do. Find those people. And bring them into your fold and your support network.

The first step is for parents to determine what their faith and values are. Ask yourself: What is it that you believe in? What are your issues of faith? What type of adult do you want your child to become? What do you want your child's world to look like? What do you want their character to be?

The second step is to commit on a daily basis to enforcing the rules and values and standards that you set for your family. It is a daily battle. And I can say as a mother of three teenagers, that I fight the culture in my house nearly everyday. I'm often tempted for a moment to give up or give in. But my husband and I determined long ago that we were going to arise each morning with the renewed commitment to enforce those values and beliefs that we believe in for our own children.

And then step number three is to teach your children the single greatest thing you can teach them -- that they have intrinsic value in God's eyes. That God loves them unconditionally, that he created them for a purpose. When children understand this, they are less likely to be involved in sexual activity. They are more likely to want to develop into the men and women that God would have them to become. And they understand that there is a place for getting moral absolutes.

The fourth step is to spend more time with family. What is so disturbing about the recent trends in media consumption is not just that it is 6.5 hours a day by kids, but that the vast majority of children say that their parents have no clue what they are watching. And that indicates that parents are becoming less involved in their children's lives while media is becoming more involved. So it is crucial that parents become more involved in their children's lives on a daily basis.

And then the fifth one is to be involved in your child's educational choices. Our children spend so many years in education and so many hours per day in education, it is absolutely crucial that parents take an active role in understanding what's being pumped into those little minds.

Crosswalk: You know, even with this great advice, some parents may still feel that the media, peer pressure, and the culture we live in has too big a pull on their kids for them to really make a difference. You wrote about the positive impact your parents had on you in Home Invasion. Could you share a little bit about your relationship with your own parents, and talk about the influence parents can have on their kids?

Hagelin: Absolutely. It's immense. I share in my chapter called "Foundation of Faith," what became a pivotal moment in my life, a very defining moment for me. It was when I was a very young girl, and I was at home alone with my father. I walked down the hallway, and I heard somebody crying -- a kind of weeping, a soulful weeping -- and I couldn't quite figure out what it was. I knew my dad was the only other person home.
