Jill Duggar and Derick Dillard are headed to another missionary trip, but is their latest venture more dangerous than their Central America project? The former Counting On stars are traveling to the high-violent city of Guadalajara in Mexico.

Duggar, 26, and Dillard, 29, were photographed with their youngest son Samuel, 8 months, at Arkansas Regional Airport.

"Pray with us for our group heading to Guadalajara today," Cross Church captioned the Instagram photo. Not present was the couple's 2-year-old son Israel.

The group is traveling to help spread awareness of a new church plant in the city with a "great gospel need."

"The week will be filled with street evangelism and building relationships to share the gospel as we help Vida Church continue reaching Guadalajara," a description for the trip read.
