Some voters are still not fully convinced that Donald Trump is really a sincere Christian who espouses Christian values. This is why the Republican presidential frontrunner is doing everything that he can to make people believe that he is indeed a man of faith.

On Saturday, Trump once again tried to woo the faith community consisting of Evangelical and African-American church leaders during a rally in Norcross, Georgia. It looked like he was able to win some of them over, according to Fox News.

"I don't know what type of legislator he would be," said Reverend Dr. Darrell Scott, a minister from Cleveland, Ohio. "But I know one thing, he is a hell of a chief executive. He's a heck of a guy."

Bishop George Bloomer from Durham, North Carolina, was also in agreement with Trump's campaign policies, saying the Republican frontrunner's beliefs are a "spiritual thing."

"Scripture about fire, purifying and consuming—what determines if it is consuming is what you put in it. It's time for us to have somebody to bring jobs to this nation and look out for the Christians," he said.

As for First Baptist Dallas Church Pastor Robert Jeffress from Texas, he said people shouldn't dismiss Trump as a fake Christian. "Some evangelical leaders believe that Christians are abandoning their values if they support Trump," he said. "I think that is much too harsh of a judgment."

Even though he has not endorsed Trump, Jeffress said evangelical leaders should be wise enough to know that Trump won't "be leading Bible studies in the Oval Office."

What they will get instead, he said, is a "leader who will solve problems—and rightly or wrongly they assume Trump is the person to do it."

Trump packs a gun

Meanwhile, Trump revealed during the CBS program "Face the Nation" that he obtained several years ago a concealed weapons permit "because I like to have myself protected."

When asked by host John Dickerson if he carries a gun, Trump answered, "Sometimes."

Just recently, a lone gunman shot to death nine individuals at the Umpqua Community College in Oregon. Trump condemned it as a "horrible" act, saying the situation might have been averted if there was someone with a gun who could have stopped the killer.

"Had somebody in that room had a gun, the result would've been better," he said, adding that "I feel much better being armed."
