This thesis suggests a particular interest in pneumatological sermons that testify to the Word of God as Living Word of God. The present kingdom of God is accomplished when the inspired Word of God is heard as the Word of God that we have now. The authority of the church comes from the proclamation of God’s Word. When today’s preachers deliver the Words of God’s revelation by speaking of the Bible through the power of the Holy Spirit, then the words that come from the mouths of the preachers are not interpreted as words of humans but as the words of God. When the word of God in the Bible is proclaimed in belief through the power of the Holy Spirit, the sermons of the preacher becomes the “Living Word of God.” For preachers to proclaim the Word of God as a revelation on the pulpit, they must depend on Jesus Christ who is the actuality of revelation, and on leading of the Holy Spirit. Pentecostalism is concerned with the ministry of the Holy Spirit working with the Word to emphasize the present condition of the Word of God. Therefore, this thesis is a pneumatological study of the living Word of God, that is, the sermon, which creates God’s present reign. The understanding of pneumatological sermons is proclaiming Jesus Christ. To proclaim Jesus Christ, the preacher must proclaim the Bible which holds the revelation, and they must receive the help of the Holy Spirit which gave inspiration to the Bible. When the church reinstates the authority of the Word, then the church can shine the light of God’s word in this corrupted world.
