An Alarm to the Unconverted, Why You Need Jesus by Joseph Alleine and published by Christian Focus Publications.
What is conversion? What does it look like? And why does it matter? Joseph Alleine addresses these questions and more in this book, pleading with the unconverted to turn to Christ. Contrasting the life of the believer with the eternity facing those who are not in Christ this passionate appeal explains not only why, but how to give your life to God.
