The work and ministry of sermonindex can be encapsulated in this one word: REVIVAL. sermonindex is not a organisation, business, or any attempt by man to build something for God. It is rather a expression of a heart burden to see the Church revived and brought back to holiness, purity, and power with God. “The mission of SermonIndex is the preservation and propogation of classical vintage preaching and the promotion of genuine biblical revival to this generation.”
