Dallas pastor Dr. Robert Jeffress confirmed to OneNewsNow on Monday that he campaigned with GOP front-runner Donald Trump over the weekend.
Jeffress, who hosts radio program "Pathway to Victory" on American Family Radio, says he was invited by the Trump campaign to pray and introduce the candidate at two Christian colleges.
Jeffress is pastor of First Baptist Church in Dallas, Texas.
"Although as a pastor I cannot officially endorse a candidate," Jeffress said at Dort College, "I want you to know that I would not be here this morning if I were not absolutely convinced that Donald Trump would make a great president of the United States."
Iowa is currently ground zero of the presidential campaign, since the Iowa caucuses are now one week away.
Trump is enjoying a comfortable first-place lead in current polling that shows U.S. Sen. Ted Cruz in second place.
Asked why Evangelicals are favoring Trump, Jeffress says that's because they want to defeat the Democrats in November and they believe Trump can win.
"Not because they believe he's the best candidate to lead Bible studies in the oval office," the pastor says of the billionaire real estate mogul, "but they do believe maybe he's the best candidate who has a chance of beating Hillary Clinton or Bernie Sanders."
Trump has drawn scrutiny among some Evangelicals when he failed to name a time he asked God for forgiveness and refused to recite a favorite Bible verse.
"Why do I have to repent or ask for forgiveness if I am not making mistakes?" Trump told CNN's Anderson Cooper last year.
More recently, speaking at Liberty University, he referred to the Book of Second Corinthians as "Two Corinthians," as it was written in his notes.
America needs a "strong Christian" in the White House, Jeffress observes, but if that's not possible, then "let's at least have somebody who can slow down the moral and spiritual death spiral that this country is in."
