About ABWE


We know that the idea of foreign missions has a lot of uncertainties, questions, and paperwork. At ABWE, we try to make yielding to God’s call and serving on a mission field, a little bit easier.

We work hand-in-hand with our more than 1,000 missionaries and their more than 500 sending churches to ensure that they are supported and equipped with a deep theological understanding, practical financial and ministry help, donor support, and unified teammates who are working together to accomplish the great work of the Great Commission.


We know that the resources we have been entrusted with are not our own; they are given to us by God through our generous and faithful supporters. We are committed to being good stewards of those resources and ensuring that they are used to make the maximum impact for the Kingdom of God.

We are accredited by the Evangelical Council for Financial Accountability (ECFA), an agency dedicated to helping Christian Ministries earn and maintain the public’s trust through responsible stewardship. Learn more about our financial commitments.
