A Sure Guide to Heaven is a profound and engaging exploration of the necessity of true conversion, penned by Puritan writer, Joseph Alleine. In this timeless classic, originally published in 1671, Alleine helps readers to discern the nature of genuine conversion while addressing common misconceptions that can lead to spiritual deception. Drawing from biblical wisdom, particularly Matthew 7:13–14, he ensures that readers are not misled into believing they are converted when they may not be.

With clarity Alleine outlines the marks of an unconverted soul, encouraging readers to take an honest self-inventory as suggested in 2 Corinthians 13:5–6. He compassionately warns those who linger on the fence about the miseries of remaining unconverted, both in this life and the next, while providing compelling motives for embracing the transformative power of faith.

The book culminates in practical "directions to the unconverted," offering a pathway to grasp the saving faith that Christ extends to all.

Though Joseph Alleine's ministry was brief, his impact endures through this work, which has been reprinted countless times. A Sure Guide to Heaven stands out as an accessible and straightforward example of Puritan writing, making it a must-read for anyone seeking to deepen their understanding of faith and salvation.
