Burroughs was much concerned to promote (1) peace among believers of various 'persuasions' (2) peace and contentment in the hearts of individual believers during what he describes as 'sad and sinking times.' "The Rare Jewel" concentrates upon this second aim. It is marked by sanity, clarity, aptness of illustration, and warmth of appeal to the heart. 'There is an ark that you may come into, and no men in the world may live such comfortable, cheerful and contented lives as the saints of God'.

Author   Jeremiah Burroughs was one of the most popular preachers in London during his time there. He was one of the Independent members of the Westminster Assembly of Divines, and a Congregationalist. He spent 6 years at a small country church (St. Margaret's, Tivetshall), which is still standing and in use. During his time in London, he preached the mornings at the church in Stepney, outside of London, where William Greenhill preached in the afternoon. In the afternoons Burroughs preached at St. Giles Cripplegate.
