Rev. Hong SungGun has devoted his entire life to leading young men and women to obey the calling of the Great Commission. He is a visionary, an excellent teacher of the Bible, and a man of the Word who has spent his life studying and practicing the Word. After having dedicated himself to the Lord in his teens, he had a powerful experience of the Holy Spirit while in university, and served as a minister to awaken his campus and the young generation. He had great influence on establishing the foundations of worship, intercession, and spiritual warfare in the Korean church based on the Word. With the conviction that only the power of the Word and the Holy Spirit has the ability to change individuals and nations, he founded the NCMN (Nations-Changer Movement ＆ Network) and is raising Nation Changers who change the world under God’s command to ‘Create change in every area of society that constitute nations and cities.’ Within NCMN, he established “Shema Bible School” for victory in the Word, “The King’s Finances School” for control over finances through the Word, and “The Changer Leadership School” to first change “myself” and then the entire nation. The Shema Bible School Program includes reading the entire Bible in 100 days. Specifically aid in this purpose, The Word: Cover to Cover in 100 Days was written to provide a systematic and multi-dimensional synthesis. Reading this book that contains the depth of God’s principles, ways, and Word in conjunction with the Bible in its entirety in 100 days will equip readers with a much more refined understanding of God’s will.
