Christian activists have come up with ingenuous ways to smuggle Bibles and other Christian texts into North Korea and are also taking circuitous routes just to be able to successfully drop off the materials as part of their goal to expand Christianity in the reclusive country.

A number of activists flew hundreds of helium-filled “Bible Balloons” — special balloons printed with the Words of God or carrying flash drives containing the New Testament — from various locations in South Korea and send them into North Korea. Others like Voice of the Martyrs Korea CEO and American pastor Eric Foley use bigger hydrogen-fueled balloons to deliver Bibles and testimonials into rural areas using GPS technology, Fox News detailed.

“The bibles are printed in another country, and then secretly taken and distributed in North Korea, usually a few at a time,” Christian humanitarian group World Help’s founder and president Vernon Brewer told Fox. “The people who smuggle bibles have to be extremely careful, changing their route and taking other precautions to avoid getting caught.”

Brewer added that the smuggled Bibles were distributed through a network of trusted Christians from the ground. He also said the small versions of the New Testament were the most popular because they could be easily passed while shaking hands or left in strategic places.

Just last month, Yonhap reported that No Chain founder Jung Kwang-il revealed that he and his co-activists produced 350 balloons with 1,000 flash drives containing portions of the Bible that were donated by U.S. students and flew them into North Korea. Jung said it was the 10th time that they had sent balloons from South Korea since June, but it would be the last one this year because of the expected change in the direction of the wind, UPI relayed.

North Korea is aware of the Bible Balloons and has been bent on shooting them down or arresting anyone seen picking up the items since the ’90s. Still, there are those who prefer to use large drones to send electronic Bibles to the Communist regime.

Bible smuggling usually has little support from outside governments, so missionaries and activists mostly have to rely on their own resources and methods to achieve the feat. Nevertheless, a Korean source told Fox that the demand for “outside” information has been increasing in the last 10 years.
