What does SIM believe?
SIM is a Christian evangelical, non-denominational mission agency. We are united by our absolute trust in the Bible as God’s living word and by our desire to make disciples of the Lord Jesus Christ in communities where He is least known. You can read our Purpose, Mission and Vision and our Statement of Faith here.
What do SIM mission workers do?
SIM engages in many types of ministries around the world, all of which are focused on making disciples of the Lord Jesus Christ in communities where He is least known. Our ministries cover four main areas: disciple-making and church planting; outreach; serving and equipping the local church; and leadership and services. To get a broader idea of what our workers do, look at our location pages or search our opportunities. All of our work is done in partnership with the local church, where that exists.
Where does SIM work?
SIM is an international mission organisation with thousands of workers serving in more than 70 countries. Many of those countries have little or no gospel witness.
How are SIM mission workers supported?
SIM workers raise prayer and financial support from churches, donors, supporters and friends and family. This team of supporters and prayer partners surrounds each mission worker. Our sending offices work with individual workers to set their budgets and help equip them to raise and maintain their prayer and financial support.
Who can work for SIM?
In short, anyone who shares our desire to make disciples of the Lord Jesus Christ in communities where he is least known and is part of a local church. Our workers come from a wide variety of denominational, socio-economic and experience backgrounds. SIM members are multi-ethnic and come from more than 70 countries. They also serve in a wide variety of ministries. The SIM family can use people of every country who have almost any skill imaginable!
How does SIM relate to other organisations?
We partner with many organisations and institutions around the world. This includes churches, denominations, educational and health establishments, NGOs, governments and more besides. A key component of any partnership we enter into is that we will not compromise our desire to share the gospel with communities who do not know Jesus.
What do the letters 'SIM' stand for?
They now stand for Serving In Mission, but first stood for Sudan Interior Mission. That was because SIM started in what was then known as the Sudan. That was in 1893, when three young men in their 20s pursued their vision to evangelise the 60 million people of sub-Saharan Africa (then known as the Sudan) who were living and dying without Christ. Unable to interest established missions—most of which said reaching the Sudan was impossible—the three set out alone, forming the Sudan Interior Mission.
