I am evangelical, but I think the emphesis on "church planting movements" and "people groups" focus is fairly anti-Christ. The IMB has a very short-sighted approach to missions that is driven by bad theology (or more precisely bad eschatology - ie. Jesus can't come back until the last people group has been "reached").
In my opinion the focus on people groups rather than people has been a detrimental approach that has caused us to look at the Church in America as a "resource" and the people in other countries as a "product". We don't have time to focus on an individual and his needs -- we are trying to open the door for Jesus to return. We have a "heart for the Oromo people", but we don't actually care about the well being of Tesguy and his family. I was actually told once in a IMB training session, "We can't waste time hunting birds -- we want the elephant."
The focus on evangelism rather than Christ has produced an emasculated Gospel that has reduced a holy God to a pathetic creator who has lost control and is now begging people to convert. Discipleship has been reduced to "evangelism" for the sake of more evangelism. Christ's demands on us have been reduced to "just receive the free gift."
No doubt some good work is being done by the IMB. There are missionaries, many who are known as disobedient, who are doing good works. But, as you can tell, I have very little impathy with their denominational approach and strategy. I hate secret agent missions (lying and decet to tell the "truth"), the "culturally sensitive gospel" (removing Christ - the stumbling block), the "western gospel" (Jesus needs you - you need to be like us - just believe and God will fix all your problems), and any other gospel than Christ crucified.
Christ has commanded us to repent, believe, and to take up our cross and follow Him. Many American mission agencies seem to have forgotten that the free grace we preach has come, and continues to come, at a very high price.
