What good does it do?

Who benefits from a mission trip? Certainly the people we minister to even if the ministry is just being friendly. Of course the missionaries are glad to have people come and help in the work (if indeed they help and don't just use the missionary as a local travel guide). Projects get completed sooner when churches partner with missionaries financially and with people to do specific tasks. People from the local churches who go benefit by having a greater understanding of how our missionaries do their ministry. They see that God works in ways that they haven't witnessed before and that expands their outlook on God possibilities. Local pastors get members who have an enlarged vision of God. I guess everyone benefits from a mission trip.
