"The Twelve" An Amazing Compilation !!
Format: Paperback
I have not been able to put this latest addition to the Passion Translation down! The Excursus on the Minor Prophets is excellent and so helpful in understanding each prophetic book. Dr. Simmons has titled the compilation "The Twelve" and it guides you on a journey from Hosea through Malachi. This is the latest endeavor is a must for anyone who desires to go deeper into the understanding the scriptures from a Godly perspective. From the introduction to each book to the in-depth notes you will be amazed and challenged at richness of God's word. A great gift for family and friends who desire a deeper understanding of scripture. You will not be disappointed.

An oldee but a goodee
Format: Paperback
I've been following Andrew for over 40 years and this is one of his long standing messages. It's an eye-opener in its revelation of what causes hardness of heart in a believer-but he doesn't stop there. He also shows the remedy.
A must-read for anyone wanting to follow in the footsteps of the Lord Jesus.
