Evangelical leader Pastor Robert Jeffress, one of the spiritual advisers to President Donald Trump, said the president was "brilliant" for skipping the climate change summit at the United Nations on Monday and speaking instead about the real problem of religious persecution worldwide.

Jeffress added that climate change teen-activist Greta Thunberg should stop fretting about melting polar ice caps and trust God, who promised us in Genesis that He would not "flood the world again" as a punishment for sin.

"I just got back from the U.N., to hear our tremendous president give a blockbuster speech on religious liberty," said Pastor Jeffress on Fox News Radio's Todd Starnes Show on Sept. 23.

“The only thing more fun than listening to him is listening to the liberals whine that he had the audacity to skip the climate summit," said Jeffress.

"I tell people, Todd, all the time, ‘This president is brilliant,’" said Jeffress. "He decides to skip attending a session on an imaginary crisis -- climate change -- and instead he chooses to lead his own conference on a very real problem, global [religious] persecution.”

"What president can you think of, from either party, who would have the guts to snub the U.N. like that and stand up for what's right?" he said.

"It's a fair point you raise," said host Todd Starnes. "This whole global warming, tree-hugging fiasco -- again, there is nothing to it. As you point out, they might as well hold a commission on the Tooth Fairy or Bigfoot, Sasquatch."

"Nobody is arguing -- we have to take care of the environment," said the pastor. "Genesis 1 and 2, we need to cultivate the Earth and keep it. But “God said He created the environment to serve us, not for us to serve the environment."

“This Greta Thunberg, the 16-year-old, she was warning today about the mass extinction of humanity" at the U.N., said Jeffress.

"Somebody needs to read poor Greta Genesis, Chapter 9," he said, "and tell her the next time she worries about global warming, just look at a rainbow. That’s God’s promise that the polar ice caps aren’t going to melt and flood the world again.”

Robert Jeffress is pastor of the First Baptist Church in Dallas, Texas, which has 13,000 members. He serves on the president's Evangelical Advisory Board and the White House Faith Initiative.

Todd Starnes's latest book is Culture Jihad, How to Stop the Left From Killing a Nation.
