Book excerpt: Derek Prince clearly explains the nature and ways of the Holy Spirit and how He works in the lives of Christians. Through the power of the Holy Spirit, the believer can experience the continual presence of Jesus, become a bold witness for Christ, acquire revelation of the Word of God, pray according to God's will, and understand the plans of God. As you understand and receive the active presence of the Spirit in your life, you will gain new power and grace for living.
