SALT LAKE CITY, Utah (CNN) — When the messages come during the dark of night, Russell M. Nelson reaches for his lighted pen and takes dictation from the Lord.

“OK dear, it’s happening,” the president of the Church of Jesus Christ of Latter-day Saints tells his wife, Wendy Nelson.

“I just remain quiet and soon he’s sitting up at the side of the bed, writing,” she said in a recent church video.

Sometimes the spirit prompts the prophet’s wife to leave the bed, though she’d rather sleep. One such morning, Wendy Nelson told Mormon leaders, her husband emerged from the bedroom waving a yellow notebook.

Russell Nelson has instituted several changes based on revelations since becoming church president in 2018.

“Wendy, you won’t believe what’s been happening for two hours,” she recalled Russell Nelson saying. “The Lord has given me detailed instructions on a process I am to follow.”
