In the third chapter of the second letter to the Corinthians, Brother Sparks emphasizes the transformative power of the Holy Spirit in contrast to the old covenant represented by the law given to Moses. He explains that believers are living epistles, written not on stone but on hearts of flesh, showcasing the glory of Christ through the Spirit. The chapter highlights the shift from a ministry of death to one of life, where the Spirit brings liberty and transformation. Brother Sparks stresses the importance of understanding the significance of the Day of Pentecost, marking a new dispensation where the Holy Spirit illuminates the Word of God, making it alive and impactful in the believer's life. He contrasts the cold, legalistic approach to Scripture with a vibrant, Spirit-led understanding that fosters genuine transformation. The essence of glory is found in the heart of the believer, where the Spirit resides, enabling a deeper comprehension of God's nature and commandments. Ultimately, Brother Sparks calls for Christians to embrace the Holy Spirit's guidance, moving beyond mere intellectual knowledge to a living relationship with God through His Word.
