Derek Prince worked at the Faith Tabernacle in Chicago, and then moved to Good News Church in Ft. Lauderdale, Florida. In May 1971 Derek Prince Publications opened offices in Ft. Lauderdale, Florida. Derek Prince Publications became Derek Prince Ministries in December 1990. The Princes traveled extensively in ministry until his wife Ruth died on 29 December 1998. The following list of countries covers their ministry from 1993 to 1998. Some of these countries were visited more than once: Russia, Germany, Kazakhstan, Hungary, South Africa, Kenya, Indonesia, Malaysia, Singapore, Turkey, Poland, Bahrain, Cuba, Colombia, Switzerland, France, Portugal, India and England. He is the author of 60 books, 600 audio and 100 videos, many of which has been translated and published in more than 60 languages. Some of the subjects that are covered in his teachings are prayer and fasting, foundations of the Christian faith, spiritual warfare, God's love and marriage and family. His daily radio is translated into Arabic, Chinese, Croatian, German, Malagasy, Mongolian, Russian, Tamil, Samoan, Spanish, Bahasa Indonesian, Tongan, Telugu, Malayalam, Kannada, Hindi and many other languages. The radio program continues to reach many people around the world. Derek Prince Ministries continued for the rest of his life to distribute his teachings and to train missionaries, church leaders, and congregations.
Demons and deliverance
As a Pentecostal, Prince believed in the reality of spiritual forces operating in the world, and of the power of demons to cause illness and psychological problems. While in Seattle he was asked to perform an exorcism on a woman, and he came to believe that Christians could be "demonized". This was at odds with the more usual Pentecostal view that demons could "possess" unbelievers, but could only "oppress" Christians. Prince believed that his deliverance ministry used the power of God to defeat demons.
Israel
Prince, who taught on many themes and subjects including the foundational truths of the Bible, was probably most noted for his teachings about demons, deliverance ministry, and Israel. He strongly opposed replacement theology. His book The Destiny of Israel and the Church argues that the Church has not replaced Israel and that the covenant that God made with the nation of Israel still stands today. Prince also believed that the creation of the state of Israel was the fulfillment of biblical prophecy. Derek states in his book Promised Land, "The central theme of biblical prophecy, as it is being unfolded in our time, revolves around the land and the people of Israel. God is carrying out His predetermined plan to regather the Jewish people from their worldwide dispersion and restore them to their ancient homeland."
Prince created the Shepherding Movement with fellow ministers Don Basham, Bob Mumford, Charles Simpson and Ern Baxter, who became known as the 'Fort Lauderdale Five.' They sought to counter what were seen as excesses within the Charismatic Movement, by emphasizing discipleship and pastoral care. The practice of 'personal submission to spiritual authorities' was considered controversial. Prince's association with the Shepherding Movement provided international exposure. After leaving the movement, he focused on his own international ministry.
Publications
Prince published many books and recorded over 600 audio teaching sermons and 100 video teachings. His books include:
