North Korean detainee shares awe-inspiring Christian message with Mike Pence. Here's what it said.

Upon arriving to the United States with Vice President Mike Pence, one of the three Americans who were detained in North Korea handed Pence a note with an awe-inspiring Christian message.

Pence shared the note on social media.

What did the note say?

It's not clear what the personal side of the note said, but Pence shared the side that included Psalm 126.

While it's not exactly clear what the Psalmist was celebrating in the poem, some believe it is an exaltation of the Israelites' return to Jerusalem after their exile in Babylon. Others disagree.

Still, the Psalm is one that celebrates deliverance from great opposition — something the Americans detained in North Korea surely faced.

Who wrote the note?

It's unclear who wrote the note and Pence did not say who it was. However, we know that the three detainees are devoted Christians.

Kim Hak-song, who was detained in May 2017 while teaching rice-growing at Pyongyang University of Science and Technology, is an ordained evangelical Christian pastor affiliated with a church in Los Angeles, according to CNN.

Similarly, Kim Dong Chul, a businessman who was accused of spying, is widely known to be a Christian missionary and was once a pastor.

"He told the churches that he was a missionary working on North Korea and sending stuff from China into the North to help poor North Koreans," a North Korean defector said of Kim.

Meanwhile, Kim Sang Duk, known also as Tony Kim, is a Christian who has been described as a "religiously devoted man," according to Patheos.
