Reis: Throughout middle school and high school I had kind of been searching. ... It twisted my thinking, it caused me to turn everything upside down and wonder, who is God? Sure, I believed in a God and I thought I understood it, but what does it mean to have a personal relationship? It was more of a process.

It was August of 2001. I'm coming home from a football practice in high school. I don't know what it was at the time, but for some reason I had a bad practice and that sounds silly but that's the walk I was going through and everything had sort of compounded.

This image of perfection that I was trying to keep up with was just weighing on me, and I needed someone to cry out to and I didn't feel like I could cry out to anyone. I was in my car and I remember it was truly my first time talking to God and saying I can't do this. It was the most authentic prayer that I prayed just saying, "I don't want to do this life alone anymore. It's just not fun." For me it was that point of salvation that I really started to say, "This is who I want to be. This is how I want to be loved. This is the man I want to become." ... I made the decision that I was going to follow Christ with all that I have after that.

CNN: How did your faith play a role in your football career? Would you have been the same person without it?

Reis: No, I know for a fact I wouldn't be the person I am without my faith. To me it's who I am; it's built the character. I want to look for ways to live out my faith in every opportunity.

Getting cut by the Falcons in 2006, my dream was over, crushed. I was about to get married, I felt like a bum. I didn't know what I was going to do. I hadn't graduated (from college) yet. So it's like, "What are you doing with me, God?"

It was a lot of searching and praying that he has a plan for my life. Little did I know I would get shipped over (by the Saints) to NFL Europe. It was amazing to have the perspective that I'm not really over there for football -- (and) to see the things that we saw: the people we were close with, the relationships that we built and to see the people who came to Christ and really started walking with him. I had an amazing season but that was secondary to what God was doing.

Then going into the NFL, people always ask about the Super Bowl: "How was it?" I always tell them the Super Bowl was great, onside kick was awesome. what I truly remember about that year, and it sounds cliché, ... was the relationships that we built. We were so close as a team. We would hold Bible studies, and I saw marriages come together.

CNN: What do you hope to accomplish with the book? What do you want the take away to be?

Reis: What we want people to take away is just to be inspired. That it's never too late to turn your life around, and this is not just from an addiction standpoint. When I go out and talk it's always live for more -- and it's living for more than this world has to offer. If we're just living for the next thing, hoping it will make us happy, it never does. We want to inspire people to be better husbands, better fathers, better mothers. We want to help people not make the same mistakes we did, and we want to give them a purpose to live for something greater than themselves.

Not everything is going to be perfect, but it can be better. We want to show the depths of how far my dad was - and not only that, but how he's changed and that's through the redeeming love of God. We can portray that love for other people and demonstrate how a heavenly father loves us and we can portray that that's a God that wants to love you and have a personal relationship with you so it's really important to us.

People want to feel like they're not alone, and you're not alone. Even a Super Bowl champion has problems in his family. It's inspiring to us and we hope it inspires others.

CNN: Super Bowl prediction?

Reis: I'm going to say the 49ers, and I think with two great defenses, I don't think it's going to be a high scoring game. I'm thinking 21-17.
