This is a most welcome development. Ligon Duncan and others have taken Matthew Henry’s classic Method for Prayer, updated the language (including the ESV instead of KJV) and put the whole thing online for free.

You can use this biblically saturated resource in numerous ways:

(1) Read the book online.

(2) Follow the thread of a keyword through different parts of the book.

(3) Work through the heart of the book via daily devotional emails.

(4) Take advantage of the Index and Table of Contents.

(5) Perform your own search of the book’s contents.

(6) Other features of this website.

I highly recommend checking it out and bookmarking it! There are few other resources as helpful for learning how to pray God’s Word back to him.
