In your chapter about doubt, you write about reconciling faith and doubt. How can the two co-exist?
Not every Christian finds it easy to believe. Obviously [this is a problem for] everybody, but I'm just going to stay with the Christian ranks. When you read the story of Lazarus being raised from the dead, a non-reflective kind of person will think, "Gee, I would have loved to have been there." The reflective person will say, "Hold on. How'd that happen? Was he really dead?" Those are all thoughts of doubt. [In John 20] Thomas said, "If I see the scars in his hands and put my hand at his side and see where the spear was driven into him, I will not believe." Thomas was a reflective person. So when Jesus came to him, he didn't shame him. He said to him, 'Here, reach out your hand and touch the scar. I want you to see this, Thomas." He blessed him, he didn't make him ashamed. But he said, even more blessed are those who have not seen and believed. There will only be a few Thomases that have the privilege of touching the hands and the feet and the side. But the rest of us must believe by faith. In my book, this chapter says doubt is ok; it's not something that's going to send you to perdition. It's part of being a reflective person.

Do you think Christians today doubt enough?
That's hard for me to answer. I find that I'm around people who are a little too quick to believe. They say 'because I hear it from some televangelist, I'm now going to believe it, or because some Christian author wrote this, I'm supposed to believe it.' So in that sense, I think too many people are gullible. The key word here is discernment. We need discernment in what we see and what we hear and what we believe.

Turning to your chapter on prejudice, you write that your own understanding of Jesus overcoming prejudice had a lot to do with your own overcoming prejudice when you grew up in the South. How so?
I'm a child of the mid-30s and I had parents whose roots are in the deep South. So I heard statements and words used that, as I grew up, I found myself increasingly uncomfortable with. It especially helped me to do a stint in the Marine Corps, where fighting right alongside me were people of color. If you do enough of that, you become colorblind. You realize there are magnificent people out there of all colors, and there are some bad people out there, of all colors. Prejudice is a learned trait. You're not born prejudiced; you're taught it. If you're standing there as a five-year-old child in a Ku Klux Klan outfit, you're learning to hate African-Americans. If you never see that, if you're around parents who teach you to love one another, it doesn't dawn on you not to come to the aid of someone in need or not to talk to someone because of color. I think there are few people like Christ who can get you beyond that problem.

In that same chapter, you imply that Jews are still prejudiced against Jesus.
Some are. You've got to admit that when there are Orthodox Jews who are around Messianic Jews, that is people who were born Jewish but who have come to faith in Christ, there is a hatred for them.

You think that's because they have a hatred of Jesus?
I think it very well may be. They do not believe that the one who came is in fact Messiah. They're still looking for the Messiah. If you place your faith and trust in one you've called Messiah, they believe that's a false messiah. So, you ask if that's a hatred toward Jesus or toward them [Messianic Jews]. I think it's a disrespect toward them, and if we're going to use the word hate, I think the hate would be directed toward the one in whom they believed. They resent the thought that the other person would trust in one who claimed to be Messiah who they say is not Messiah.

Well, hatred of Jesus certainly isn't part of the many alliances forming between Orthodox Jews and conservative Christians these days. They're coming together on gay marriage, on abortion, on Israel. How do you view these alliances?
What they're agreeing on is ethical issues, moral issues. I'd be the first to say that some with whom I would not agree spiritually, as it relates to their rejection of Christ, I would agree with their position as it relates to abortion, or one of the issues you have mentioned. I think we can align with one another on those issues, and that's great. I don't think that just because a person rejects Christ that he doesn't have any opinion I can respect or he has nothing to offer that I can't learn from. That's stupidity and that's ignorance.

You've said that one of the most important principles for life is that marriage is forever, to the same person. But your book devotes entire chapters to getting through divorce and remarriage. What do you really think about marriage?
If it's an ideal world, then the ideal plan is one man for one woman for all of life. However, the ideal is that I never have germs. Sin is a reality. People disobey. Affairs happen. Broken vows occur. I think because of that, there is the permission on rare occasions for divorce and remarriage. I think it's the exception, rather than the rule. It's permitted rather than applauded. But I've even married couples who have been married before, if I've been convinced that they've thought it through, that they had reasons for divorce.

In certain cases, you're not under bondage to stay with a person.
