Bush was born in Argentina, but was raised in Brazil. In 1970 he graduated from the University of North Carolina in Chapel Hill, N.C. in economics and worked in Business Consulting for Arthur Andersen Consulting in Chicago before deciding in 1973 to devote his life to Christian ministry. After his graduation from theological seminary in 1978, he traveled to San Salvador, along with his wife Doris, to serve at the Iglesia Nazaret as senior pastor. Bush led the movement of missions called COMIBAM from Latin America during its initial phase and later served as CEO of Partners International from 1986 to 1992, an organization that seeks to grow communities of Christian witnesses in largely non-Christian areas by partnering with indigenous Christian ministries. He served as the international director of the AD2000 & Beyond Movement from 1989-2001.
The 10/40 Window & Transform World
Luis and Doris together coined the term 10/40 Window which focused on the region of the world with greatest human suffering combined with least exposure to Christianity. Transform World was the name given to the first global event in Indonesia in 2005 when Luis was asked to serve as international facilitator for other related events processes. Transform World Connections exists to build a community of servant-catalysts engaged in God’s mission of transformation that results in the healing and blessing of the nations.
Bush completed a PhD in Intercultural Studies from Fuller School of World Mission in 2003. The study of catalytic antecedents of today’s mission led to a World Inquiry conducted from 2002 to 2004 involving participants from more than 700 cities.
