(OPINION) When it comes to using television and radio to spread the gospel of Jesus Christ, Billy Graham, and Franklin Graham have worked to maximize their impact over the decades.

But now Franklin Graham has a somewhat dire warning to those who use these mediums to spread Good News. “The storm is coming where we’re going to be off the radio and television and the internet,” Graham said.

During his 29-minute keynote speech in Orlando, Florida, the evangelist gave examples of the challenges facing Christian media. He also offered advice to those concerned about religious persecution in areas like data centers, banking, and insurance.

“If you’re not going to preach the gospel, you don’t have anything to worry about. If you’re not going to talk about sin, you’re not going to have anything to worry about; but if you’re going to proclaim the gospel, they’re going to try to shut you up.”

Franklin Graham shared examples of the power of media in his early ministry and how his father used it so effectively. But in between standing ovations, stories, and laughs, he charged the crowd to be prepared, to start thinking now about a world where standing on God’s Word could be punishable by law. “Jesus told us the world hated [Him] first and they’re going to hate you,” he said. “If you stand for Christ, the world is going to hate you.

Graham said believers in the United States are “living in a cancel culture that wants to destroy Christian organizations,” adding that “we cannot back up, we can’t retreat, don’t apologize for the Gospel — just declare it, just preach it.”

Earlier this month, Graham gave the keynote address at the commencement ceremony for graduates of Liberty University, the prominent Evangelical academic institution based in Lynchburg, Virginia.

In his remarks to graduates, Graham said that he was praying that “this class will stand for truth,” giving a warning that “our world is changing” for the worse.

“It has changed so much, just in the time since you set foot on this campus a few years ago,” said Graham. “Think how much it has changed. The increase in violence, the moral decline.”

“I can’t help but think that the heart of God is grieved as He looks at our world today. Our country. Oh, I love our country, but it’s in a downward spiral morally, spiritually, economically, politically.”
