We partner with evangelical churches of all denominations to send workers into communities where Christ is least known. We serve on every inhabited continent in the world and in more than 70 countries. We are united by our desire to share the good news of Jesus with those who are living and dying without Him.
Our workers serve in a huge range of ministries, from church-planting and youth work to theological education and Bible translation; from hospitals and clinics to universities and colleges; from accounting and finance to human resources and administration; from agriculture and relief work to small businesses and friendship evangelism.
