4G Mission Theory

Acts 1:8 But you will receive power when the Holy Spirit comes upon you. And you will be my witnesses, telling people about me everywhere—in Jerusalem, throughout Judea, in Samaria, and to the ends of the earth.”

4G mission theory demonstrates how all 4 geographies of mission are essential and that every mature Christian community should seek to find their involvement in all 4 without prioritising any one over the others.

Travel and international communications in our modern world have changed. 4G mission theory uses measurements other than geographic distance to redefine the 4 geographies of missions.


The four geographies of 4G mission theory are:


G1 Jerusalem

G1 is your home city, your own local community. This includes all sub-cultures represented in your fellowship. This is where the commandments to love one another and the instructions on edifying one another first find their meaning. Our ministry to each other is essential to the life of the church. 


G2 Judea

G2 is your homeland and your countrymen. The are the people that you share space with on a daily basis, and many of them are ready to hear about Jesus from you. Relationships always take effort but in G2 you should share most of what forms your culture and worldview in common with those you desire to reach.  This includes vital ministries in post-Christian contexts in Europe and elsewhere. Ministry in this geography requires some cross-cultural adjustment, and requires you to step outside your comfort zone. G2 ministry is essential to the life of the church. Our Christian heritage should not be taken for granted.  


G3 Samaria

G3 is ministry to our neighbours. The Samaritans are those who are nearby but nothing like you. They may be your enemies or the people who you struggle to respect. There may be hostility reflected back at you as well. This includes immigrant communities within reach of local churches and also overseas ministry in countries that associate with western civilisation and practice. Peoples in this category are probably members of a major world religion that you do not share in common. Culture and language learning are significant but usually a program or institution can be found teaching it.  Many of the world's largest unreached people groups are here. Ministry in this geography is essential and we need to train the whole church to accomplish it well. 



Ends of the Earth

In all corners of our world there are indigenous people groups who live in the places where our maps end. The geographical distance to them is measured from the point you get off the plane. These people are often oral, nomadic and minorities.  Some G4 peoples have not contacted the outside world.  There are many unreached people groups in this category, as well as many encouraging missionary success stories. Ministry in this geography is essential if we are to fulfil the task that Jesus has given us.
