Little Girl for Sale. The message is never quite so blatantly stated, but it is a reality just the same. All around the world, but particularly in developing nations, little girls and boys are up for sale—or available to rent by the hour. Last week I led a short-term team to Mexico City, where we visited missionaries Jason and Nicole (last name withheld for security purposes) whose multi-faceted ministry includes rescuing children from sex trafficking. Mexican children regularly disappear, never to be heard from again, and as I traveled with Jason and Nicole, it became apparent to me why Mexico City is a prime target for traffickers.
