I'm just as concerned that there are people in my own neighborhood that need a Savior and do not know Jesus Christ. 

can you imagine no one in your whole nation - no one that even speaks your language - that is a witness for Christ?  Not just in your neighborhood but no one in your whole town, state, country...  Praise God your neighborhood has someone like you... shame on us that whole nations have no witness at all...

to be honest, i have a bit of a problem with this vision to be honset with you. what does this say about god, the kingdom, etc etc? that god's hope is mediated....that it is known only through the spoken language of another....that it's kin to social darwinism.....that those on the "wrong side" of the tracks are just out of luck...that language itself is wholly self-referential?

i'm not for a second suggestig that my issues equate to a thought that we ought to "not go" - far from it. go - be - engage - here - there - wherever.

but at some point, i think we have to come to grips that god is god - that he is wholly other - without need - and that he has created all that is.

There's a weird tension in your comment pax.  God is God.  No one or thing can change that.  It was God's desire to bless others through Abraham - eventually through his line... Jesus Christ.  The revelation of that message has always been intentionally God and intenionally man in cooperation - by God's design.  Since the beginning of creation God has given man roles and responsibilities to carry out on the earth.  One of the last revelations given was to go and make disciples of all nations.  Would you have made this same comment to the disciples? to Christ?  The Joshua Project has simply tried to bring clarity to the reality of our mission.  Maybe I'm missing the point that you're making.

Finally, when you say "that god's hope is mediated"... are we not ambassadors is not God making his appeal through us or are you saying you have a problem with Paul's theology.  When you say "that it is known only through the spoken language of another"... do you take offense then at God because he decided on a people group and wrote in their language and commanded them to live a certain way so that the nations around them would be reconciled to God.

It sounds more like you're not willing to accept that God has given us the Gospel to be stewards of it among the nations.  It sounds like what you're saying is that it's God's fault if there are people groups that have not heard.  It sounds like you're saying that God wasn't being serious when he repeatedly commissioned those who were following him to make disciples of others and be his witnesses to the ends of the earth.

I'm not sure that it is what you're saying that's just what it sounds like... it's just a wierd tension that you're presenting here that doesn't really provide any solid answers and I would think it lends itself to apathy among Christ's followers to obey all that he has commanded.
