We have been empowering local people to multiply dynamic groups of believers all over the world for more than one hundred years, but there are still many communities without a Christian witness.

We want YOU to be part of the work and GO SERVE God on either a
short term trip or as a longer term missionary. There are heaps of different areas within which you can serve. Please ask us about short term trips, gap years, or long term service.

OMS is committed to the principle that ‘the sons and daughters of a nation will best win that nation for Christ.’  OMS has therefore always sought to fulfill the Great Commission through a distinct four-fold ministry strategy.

    1) multiplying disciple-makers: We become vessels of Christ, leading people to a life-changing relationship with Jesus, teaching them to follow Him and invite others to do the same.

Multiplying churches: We encourage, empower and support local churches to multiply themselves in their own communities and beyond.


    3) Multiplying missionary movements: We inspire and equip Christians from many nations to follow a cross cultural missionary call.  Establishing missionary sending entities in partnership with the local church.

    4) multiplying Leaders: We equip leaders in our training centers and seminaries worldwide so the future leaders of the national churches will be from within that country.

"I will instruct you and teach you in the way you should go, I will guide you with my eye." Psalm 32:8

OMS History


One Mission Society was established in 1901 in Japan by Charles & Lettie Cowman, E.A. Kilbourne, and Juji Nakada. Originally we were known as ‘The Oriental Missionary Society’ (OMS), with our work confined to the Orient. After World War II the work and ministries of OMS expanded beyond Asia into other countries on five continents. This necessitated a name change to One Mission Society, as we are known today. As a global mission, we have more than 400 missionaries serving in 20 countries plus associate workers and ministries in 23 additional nations. Missionaries serving under the auspices of OMS are from many countries including traditional missionary sending countries as well as developing nations.
