GRAHAM: No. I mean, we're so early. But I do like Sarah.
AMANPOUR: Well, there are people in right now. Would you support Mitt Romney, would you support --
GRAHAM: I've met --
AMANPOUR: -- Donald Trump?
GRAHAM: I've met Mitt Romney. No question he is a -- he's a very capable person, he's proven himself. Donald Trump, when I first saw that he was getting in, I thought, well, this has got to be a joke. But the more you listen to him, the more you say to yourself, you know? Maybe the guy's right. So, there's a --
AMANPOUR: So, he might be your candidate of choice?
GRAHAM: Sure, yes, sure.
AMANPOUR: President Obama has come to you and your father, you've all prayed together. How would you say he's doing?
GRAHAM: I think he's a very nice man. I think he's a very gracious person. But I think our country is in big trouble.
AMANPOUR: Does it bother you that people ///like Donald Trump for instance right now, are making another huge big deal about birth certificates and whether he's a Muslim or a Christian and where he was born?
GRAHAM: Well, the president, I know, has some issues to deal with here. He can solve this whole birth certificate issue pretty quickly. I don't -- I was born in a hospital in Ashville, North Carolina, and I know that my records are there. You can probably even go and find out what room my mother was in when I was born.
I don't know why he can't produce that. So, I'm not -- I don't know, but it's an issue that looks like he could answer pretty quickly.
As it relates to Muslim, there are many people that do wonder where he really stands on that. Now, he has told me that he is a Christian. But the debate comes, what is a Christian?
For him, going to church means he's a Christian. For me, the definition of a Christian is whether we have given our life to Christ and are following him in faith, and we have trusted him as our Lord and Savior.
That's the definition of a Christian, it's not as to what church you're a member of. A membership doesn't make you a Christian.
AMANPOUR: Do you believe him when he tells you he's a Christian?
GRAHAM: Well, when he says that, of course. I can't -- I'm not going to say, "Well, no, you're not." God is the only one who knows his heart.
AMANPOUR: Coming up...a religious renewal in the unlikeliest of places... New York City. I'll talk to a pastor who battles the demons of Wall Street greed and the dog-eat-dog culture of success. All that and a special Easter Sunday roundtable...when our special edition....God and Government continues.
AMANPOUR: Reverend Tim Keller came to New York City with a daunting mission....to bring the gospel to a town that's all too often written off as a modern-day Sodom and Gomorrah. He came to preach to the Masters of the Universe: Wall Street wizards, media moguls..... but he started with a mere 75 members...That was 22 years ago. Then, a watershed moment: September 11th. On the Sunday after the attacks, 5000 people showed up at his Redeemer church. And ten years later, they are still lining up.
There's no grand cathedral....not even a small chapel. Keller rents spaces around town each Sunday, spreading the good news in a city long thought too tough to tame. I spoke with him at one of his borrowed pulpits: First Baptist church on Manhattan's upper west side.
AMANPOUR: First, thank you for joining us, Mr. Keller.
PASTOR TIM KELLER: Glad to be here.
