Donald Trump says he has "very a great relationship with God," and evangelical Christian voters in Iowa.

Appearing on CNN's "State of the Union," Trump said that despite his multiple marriages, celebrity life and pursuit of riches, he does not regret saying he does not ask God for forgiveness.

"No," Trump said. "I have a great relationship with God."

"I live a very different life than probably a lot of people would think," Trump, who does not drink alcohol, explained.

"I like to be good," he said. "I don't like to have to ask for forgiveness. And I am good. I don't do a lot of things that are bad. I try and do nothing that's bad."

"I have a very great relationship with God and I have a very great relationship with evangelicals," he said.

Despite his two divorces and famous reported extramarital affair with Marla Maples, who became his second wife, Trump said sinful ways are behind him.

"I'm talking about over the last number of years, I'm leading a very good life," he said. "I try to lead a good life, and I have. And frankly, [that's] the reason I'm doing so well in Iowa."

Trump suggested his chief rival in Iowa has more work to do with the Lord. The real estate mogul said Sen. Ted Cruz, R-Texas, showed his colors by attacking "New York values" during Thursday night's Republican debate.

"He came across as very strident and not a nice person," Trump said. "And people don't like that."
