Joshua Adjabeng was born in Atonsu, Ghana on October 5, 1950. He was the oldest of of nine children. His father was a storekeeper and cocoa farmer and his mother was a homemaker. It was a Christian home (his father was an elder in the local congregation of the Church of Pentecost) and Adjabeng himself gave his life to Christ in 1967. After this he became an active leader in various Christian clubs and activities, including the Scripture Union at his high school, where he met his future wife, Rose. After graduating in 1970, he enrolled at the College of Art of the University of Science and Technology in Kumasi, Ghana. After a two year predegree course, he graduated in 1976 with a B.A. in Graphic Design. While on campus he was very much involved with the campus chapter of both Campus Crusade for Christ and the Ghana Fellowship of Evangelical Students, a sister organization to the Inter-Varsity organizations existing in many other countries. After graduation he worked for a year for the literature committee of the Christian Council of Ghana and then from 1977 to 1979 he was on the staff of an ad agency in Accra. From 1979 on he became the manager of the press of the Church of Pentecost, which published tracts, books, Sunday school materials, the magazine Pentecost Fire and other material for the church throughout West Africa. He also became one of the youth leaders of the church and served on the board of the African Christian Press. He came to the United States in 1985 to take the Communication program at the Wheaton College Graduate School. He completed the program in 1988 and returned to Ghana and the Church of Pentecost Press. He and Rose had three children.
