I've only had these two commentary books for a few weeks but have used the New Testament book a lot (doing a Bible study on the book of John). The explanations are so easy to understand; I'm very pleased with my purchase.
I have been a pastor over 20 years now and these commentaries are some of the best that I have come across. The explanations are clear and concise for both laity and ordained. I have got a great deal of sermon material as well as teaching material here.
