A Call to the Unconverted to Turn and Live: And Accept of Mercy, While Mercy May Be Had; As Ever They Will Find Mercy, In the Day of Their Extremity from the Living God

Richard Baxter was an English Puritan church leader, poet, hymn-writer, theologian, and controversialist. Dean Stanley called him "the chief of English Protestant Schoolmen". After some false starts, he made his reputation by his ministry at Kidderminster, and at around the same time began a long and prolific career as theological writer. After the Restoration he refused preferment, while retaining a non-separatist Presbyterian approach, and became one of the most influential leaders of the nonconformists, spending time in prison.
