Take the challenge - study Arabic! There are many ways of doing it, from studying at home from a book to taking a few years out for full-time study. I spent two years at a language school for Christian workers in Amman, Jordan. The Kelsey Arabic Program is an excellent place to go if you "wish to work in churches and Christian ministries serving Arabic speaking peoples."
Modern Standard Arabic.
There are various resources available online. LangMedia has a good set of introductory materials for Jordanian Arabic, including audio and video clips.
