The Unity of the Church Essential to the Conversion of the World: A Sermon, Preached Before the Directors and Friends of the London Missionary Society, During Their Anniversary in May, 1846, in the Church of St. Mary, Spital Square, London

"The Unity of the Church Essential to the Conversion of the World" by J. H. Gwyther is a sermon delivered during the anniversary of the London Missionary Society, written in the mid-19th century. This religious discourse emphasizes the crucial connection between the unity of the Christian Church and the conversion of the world to Christianity. Gwyther's address is deeply rooted in the theological context of the period, promoting a message of communal strength and cooperation among believers, focusing on the teachings of Christ regarding unity. In this sermon, Gwyther explores the theological implications of unity within the Christian community, particularly as it relates to the efficacy of missionary work. He articulates that the power of Christian witness and the spread of the Gospel are contingent upon believers coming together as one. Gwyther outlines three main points: the objective of the Savior's prayer for unity, the means by which this unity can be fostered, and the reasons why it is imperative. He posits that only through a concerted effort towards unity can the church effectively reach the world for Christ, making a poignant call for believers to set aside divisions for a greater collective purpose of evangelism and witness. The sermon serves as an urgent plea for the church to embody the love and oneness that Christ desired for His followers, which, according to the author, is foundational for successfully converting the world.
