A Puritan classic on holiness updated to modern English.
First published in 1692, The Gospel Mystery of Sanctification has been recommended by John Wesley and others.
Andrew Murray found it so helpful that he republished it in 1884, saying this in the Introduction:
“Let me, in conclusion, urge any believer who longs to discover or to understand better the secret of a holy life, to take time for the study of this little book, especially its Third, Fourth, and Twelfth Chapters.”
Here are those chapters, plus two others, in modern English.
