Here is a way to help Dr McMahon's ministry. I recently purchased 'The Saints Spiritual delight & A Christian on the Mount' by Thomas Watson. This has 2 treatises - the largest being a practical and very helpful guide to meditation. If you want a very helpful comprehensive guide to meditation on the scriptures, this is the book for you! The Saint’s Spiritual Delight, and a Christian on the Mount by Thomas Watson (Paperback) - Lulu
