How does God bring His Word into our lives? The answer is: by the Holy Spirit. By the Spirit the Word was revealed and written. By the Spirit the Word became flesh and dwelt among us. By the Spirit the Word roots itself in the hearts of sinners and produces fruit. Calvin recognized long ago that the Holy Spirit is the bond of union between believers and Christ. Jonathan Edwards said that the Spirit is the sum of all Christ bought for His people with His precious blood. How precious then is the Spirit, and how important to know Him and His ways! In this book, a team of pastor-theologians uncover the rich biblical teachings about the work of the Holy Spirit. How was the Spirit involved in the human life of Jesus Christ? What is a spiritual person? How does the Spirit open the mind of sinners to trust in Christ? What does it mean to serve God in the power of the Spirit? How does the Spirit’s sovereign work relate to our responsibility in evangelism? These questions and more are addressed in this book.
