This is a scarce book by a little-known Puritan, but was widely read and loved in his day. The premise of the book is that one should never waste time when alone, for that time could be spent in meditating upon God. Ranew covers what meditation is, that it is a duty for every Christian, how we can go about that duty, and how meditation is a spiritual pleasure.
Nathanael Ranew studied at Emmanuel College, Cambridge, and in 1627 was ordained in the Church of England. Following the Act of Uniformity of 1662, Ranew along with many other Puritans left the Church, though he would continue to preach and minister to the people of Essex.
