Mission Team

Our GNN team consists of experts from different countries. Each of them has years of ground level experience from mission fields. What unites us, is the vision of evangelizing the yet unreached peoples of the world.

In Finland we promote this UPG* vision via weekly radio programs and arranging “vision casting” events all over the country. Those interested can subscribe to receiving the GNN Newsletter via email. The most visible part of our local mission is Vantaa International Christian Fellowship (VICF) in Tikkurila. [vicf.fi]

In foreign missions we partner with parties who share the same vision. This is actualized practically in training and sending Indonesian pioneers amongst the unreached tribes. We also work in other ASEAN countries. In East Africa we have expanded partnership to Uganda and Tanzania.

The three-week UPG* course we piloted in Dar es Salaam in the summer of 2019 activated half of the participants to go amongst the unreached in their nation. They are focusing on at least three new tribes. We also organize further training to the pioneers.

Based on our experience in Tanzania, we are tailoring a suitable training also in other East African and South East Asian countries; this is becoming a new opening for us in addition to our existing pioneer work.

* UPG is short for Unreached People Groups, meaning those tribes, tongues and cultures of the world that have not yet been reached with the Gospel.
