"The Greatest Thing in the World" is the enduring sermon on love and kindness by Henry Drummond, a respected and popular nineteenth-century Scottish evangelist, scientist, speaker, and writer. Drummond was well-known during his lifetime for his efforts to bridge the gap between the scientific world and the religious world, most notably in his 1883 work "Natural Law in the Spiritual World". He was also a popular and inspiring public speaker and his 1890 sermon "The Greatest Thing in the World" remains widely read and quoted the world over. The sermon is a powerful sermon exploring the Biblical verse 1 Corinthians 13 and Paul's writings on love, which remains as relevant and meaningful as when it was first given. It is considered by many to be one of the most extraordinary and moving descriptions of the importance and power, that love has in everyone's daily life and spiritual practice. Drummond also provides practical and useful guidance for every Christian to live a gentler, kinder, and more compassionate life. "The Greatest Thing in the World" will touch the heart of everyone who reads its timeless message and is an important addition to the libraries of the devout and nonreligious alike.
