What do mission organizations do for these people?

Most like Don Richardson, the author of The Peace Child, believe that they are helping they are bringing the word of God to these people. He believes that the way he is going about bringing the word of God is better then the other groups would of done it. That he isn’t pushing his ideas or beliefs on them he is just showing them new ways that they might actually like better then their own. He is a strong believer in what he is doing as a missionary.
I find that this article makes him seem extremely bias. Even though it does show other points, for the most part Richardson is putting down the other side and favoring the side he believes in. He is not really just stating facts about the topic, he is more so in a way trying to make the reader lean to what he believes in.
I believe that missionaries yes in most cases help out cultures that haven’t been exposed to the word of God as much as we have, but I also believe that we are trying to change their culture or make them conform by going into THEIR homes and telling them their believes even though for the most part they are not pushing it on them, I feel like they are. The reason for this is the people survived as long as they did on their customs and believes, why do we need to go in there and change it or even give the idea of a change.
