Josiah Venture is the missions organization that I served with as a high school student and then full-time for 5 years. I cannot more highly recommend a summer internship for college students. There are internships for evangelical camps with music, media, sports. Less than 1% of youth in Central and Eastern Europe are believers. The need is great!
Deadline to apply is January 15, 2019. Countries to serve in: Croatia, Czech Republic, Estonia, Latvia, Ukraine, Slovenia, Slovakia, Poland, Bulgaria, etc.
