Like most pastors, I love reading. I bought There Really Is a Difference! A Comparison of Covenant and Dispensational Theology about eight years ago and have marked it up thoroughly over the years. It's a simple and fast read. Renald (Rennie) Showers is a great author, He went home to be with the Lord in April 2019. Mr. Showers explains the difference between Covenant Theology and Dispensational Theology concisely. I have given this book to laymen in our church as well as to some young preachers. I highly recommend it.
