When it comes to understanding what true conversion is, how easy we are deceiving ourselves with false signs of conversion, and how man is to be converted to biblical Christianity, there are not many books like this. With the now renowned Puritan precision in handling God's Word, the Bible, Joseph Alleine (1634-1668) will take to through all these facets of conversion, true and false, but he will not do it as a mere intellectual exercise, but always accompanying it with a constant call to examine yourself to see whether you are in that true faith, to test your own conversion. This book has been instrumental to the conversion of many other preachers and ministers. This book has been originally published in 1671 under the title "Alarm to the Unconverted. A Treatise on Conversion." The current edition has been proofread, typeset for eBook readers, and slightly updated for modern readers. About the author: Joseph Alleine (1634-1668) was born into an English Puritan family, studied at Oxford under John Owen and Thomas Goodwin. He started his Gospel ministry in Taunton, England, but was soon evicted from his church under the Act of Uniformity, in 1662, being then imprisoned twice for holding secret church meetings. Soon after his release, in 1668, he died on November 17, 1668.
