I can’t tell you how many times in my life I have heard someone say the equivalent of, “Don’t we have enough to do at home? Why do we need to go overseas? Shouldn’t we take care of our neighborhood first?”
When Sherrylee and I were newly married and committed to going to Germany with our newly-formed mission team, I asked a very prominent preacher whom I knew for help raising support. Without thinking about what the implications were, he said, “Man, if only you weren’t going overseas!” I mistakenly took this as criticism back then, but I know now that what he really was saying was that American Christians prefer to support local over foreign outreach. Bad decision!
Remember how God allowed persecution on the earliest church in Jerusalem and “scattered” people, forcing them into other countries, even to the Gentiles (Acts 8:1,4,19-20). I don’t think He used the same technique with American Christians—although WWII was the real beginning (not the earliest) of foreign outreach in churches of Christ—but I do believe that He has worked in time and space in our day to wipe away our tepid excuses for not sharing the Good News with people different from us.
Look at this snippet from Wikipedia about U.S. Immigration:
As of 2006, the United States accepts more legal immigrants as permanent residents than all other countries in the world combined. Since the liberalization of immigration policy in 1965, the number of first-generation immigrants living in the United States has quadrupled, from 9.6 million in 1970 to about 38 million in 2007. 1,046,539 persons were naturalized as U.S. citizens in 2008.
If Christians hesitate to “go into all the world,” then why shouldn’t God bring all the world into our neighborhood? It’s not punishment—it’s who we are and what we are about!!
Let’s Start Talking is best known probably for its short-term, overseas mission programs, but as early as 1990, LST was also training Americans to reach out to international students, immigrants, and non-English speakers in our universities and neighborhoods. FriendSpeak is LST’s program for training churches to reach out cross-culturally in their own communities—and it is huge!
Rather than tell you about it, I want to give you a link to the Christian Chronicle which just ran an online article and asked for feedback from those who might have used FriendSpeak in their churches. Just click this link and you will see firsthand what can be done here at home for the whole world:
Local versus Foreign—not even a legitimate argument anymore—if it ever was. There is only, “Who can I talk to today—and who can I talk to tomorrow—and who will talk with those people over there? Sure, I will.”
