Derek Prince discusses the distinction between the Baptism in the Holy Spirit and the fullness of the Holy Spirit, emphasizing that while many believe they are filled with the Spirit upon baptism, the New Testament presents a more nuanced understanding. He highlights that the baptism is an immersion into the Holy Spirit, while fullness involves being continually yielded to and possessed by the Spirit in every area of life. Prince stresses the importance of recognizing unyielded areas that may allow for spiritual bondage and the need for deliverance through Jesus Christ, truth, and the Holy Spirit. He concludes by outlining the conditions for deliverance, which include confession, renouncing sin, forgiving others, and calling upon the Lord.
