Evangelist Franklin Graham said that prayer – and God’s answer to it – helped Donald Trump and Mike Pence pull off “the biggest political upset of our lifetime.”

Graham, president of the Billy Graham Evangelistic Association and Samaritan’s Purse, did not formally endorse Trump, but he has shown his support for the nation’s 45th president.

“Did God show up?,” Graham wrote on Facebook on Thursday morning. “In watching the news after the election, the secular media kept asking ‘How did this happen?’ ‘What went wrong?’ ‘How did we miss this?’ Some are in shock. Political pundits are stunned. Many thought the Trump/Pence ticket didn’t have a chance. None of them understand the God-factor.”

Evangelical leaders from the religious right – including Pat Robertson, Tony Perkins and Ralph Reed – stood by Trump during a heated election season.

By Wednesday morning, Christian leaders across the United States also extended congratulations and prayers to the president-elect.

Perkins, president of the Family Research Council, showed support for Trump and his plans to “make America great again.”

Graham also congratulated the president-elect and vice president-elect on their win.

“One thing is for sure, we need to pray for our new president, vice president, and our other leaders every day – whether we agree with them or not,” he wrote Wednesday on Facebook.

“They need God’s help and direction. It is my prayer that we will trying be ‘one nation under God.’ ”

He reiterated that statement again Thursday.
