In writing about Spirit Filled Spirituality Boa discusses Walking in the Power of the Spirit, Gifts of the Spirit, and Openness and Discernment: A Balance.
In the first chapter he discusses how the power the Spirit is predicated on enlightenment of the Word. Many believers overemphasize either the Spirit (Spirit Centered Believers) or the Word (Word Centered Believers). Both are needed to unite the mind and the heart so that they reinforce each other. He reviews briefly the three major Spirit-centered movements of the 20th century: Pentecostal, Charismatic, and Third Wave. Basically there are two ways a person is filled with the Spirit. One is manifested internally as translated from the Greek word pleroo, and the other externally, translated from pimplemi.
The next chapter reviews the purpose and nature of Spiritual gifts. The church is a diverse group of believers with different gifts incorporated into a single body united in purpose and call. Boa gives us 12 principles describing the nature of gifts. Based on the lists in Romans 12, 1 Corinthians 12, and Ephesians 4 he describes the various gifts, and adds other singular ones found in scripture.
The final chapter expands the discussion on how to balance openness to the Spirit with discernment based on knowledge of the Word. The strengths and weaknesses of an exclusively Spirit centered approach versus exclusively Word centered approach are outlined. Boa points out once again the need to balance truth and power, and Word and Spirit to guide our inward and outward journeys. He concludes by offering advice on how to appropriate the power of the Spirit.
