The Lord burdened the Parks for the people of Asia. After joining BMM in 2006, they served in a Creative Access Nation, where they witnessed lives transformed by God's power. In 2015 Lord orchestrated circumstances that brought the Park family back to the US. Although their location changed, their heart for the Asian people did not. They now serve as Campus Bible Fellowship missionaries at the University of Iowa. About 75 percent of the university's international students are from Asian countries. The Lord has graciously saved scores of students who have, in turn, taken the gospel back to their home countries. Many students have returned to locations where traditional missionaries are not allowed. This is a further extension of Christ’s command to make disciples of all nations, as the Park family strives to reach the nations from Iowa City.
