The angels in Isaiah's vision of God s heavenly temple (Isa. 6) used threefold repetition to praise His holiness, the superlative form of emphasis in the Hebrew language. Their cry tells us that nothing is as significant as the holiness of God. Tragically, the holiness of God has been obscured in our time, and as a result, the church's doctrine and ethics have been tarnished, entertainment has replaced worship in many places, the Gospel is misunderstood and neglected, and the church assimilates itself to the culture instead of seeking to transform it through the preaching of God's Word. Holy, Holy, Holy: Proclaiming the Perfections of God offers a corrective. Here, the holiness of God is defined, explored, and praised by a lineup of leading evangelical pastors and scholars, who show how it affects our worship, doctrine, and personal walks with Christ. Adapted from the lectures at the 2009 Ligonier Ministries National Conference, Holy, Holy, Holy unfolds the character of God and the holiness that sets Him apart. Here is high theology in understandable language, bringing deeper knowledge of God and promoting love for Him.
