(CNN) Shortly after former Trump national security adviser Michael Flynn pleaded guilty Friday to lying to the FBI about conversations with Russia's ambassador, former FBI Director James Comey shared a justice-minded verse from the Bible on Twitter and Instagram.

"'But let justice roll down like waters and righteousness like an ever-flowing stream,' Amos 5:24," Comey wrote, referring to the Bible's book of Amos.

Comey tweeted the same biblical passage in November after President Donald Trump called the former FBI director a "liar." Comey, a United Methodist and one-time Sunday school teacher, said it's his "favorite scripture verse."

In a statement Friday, Flynn also referenced religion, saying he acknowledged that his actions "were wrong, and, through my faith in God, I am working to set things right.

"My guilty plea and agreement to cooperate with the Special Counsel's Office reflect a decision I made in the best interests of my family and of our country. I accept full responsibility for my actions," he said.
