Luke 24:47 (ESV)
and that repentance and forgiveness of sins should be proclaimed in his name to all nations, beginning from Jerusalem.
I spent a couple years working with the Apaches while in Arizona. It was a disappointing experience. It was not the fault of the Apaches but rather the "Christians." I had never seen so much selfishness as the churches that descended down upon that reservation like vultures. Essentially what I witnessed was an industry of tourism built upon the backs of the poor that allowed a bunch of people to feel good about themselves at the expense of the people we were trying to reach.
I witnessed indoctrination, baptisms out of coercion, emotional manipulation, kids taken from their parents for extended stays, racism, and even abuse.
Success is not measured by going home and telling your church you baptized twenty second graders during your mission vacation. Those same kids will get baptized again the next week when another church comes or "ask Jesus into their heart" when yet another church comes. It's all the same to them.
Kids will do pretty much anything for candy, and candy is cheap. The gospel cost too much apparently, to transport from the Midwest to Arizona. The mission trip you took that "Changed Your Life" most likely did nothing to change the people you were supposed to be helping.
They need longterm missionaries willing to model Christ. People who will teach them the truth, respect them as people, and who realize they are guest upon the reservation.
We can't be WASP descending upon a people stinging them with white man's religion. Instead we all need to follow the man from Palestine who died 2000 years ago to unify the nations, and to make us all the Kingdom of God. Until the Midwest can let go it preconceived notion of "This is how you do church" it's never going to be able to meet the people of the Southwest were they are, spiritually or geographically.
