John McArthur is a very reliable bible teacher. He provides commentary related to the history and culture of the time relevant to the passages he is commenting on. He will insert background information that helps to place the scripture in context, and of course, most important of all, he always uses scripture to interpret scripture. I routinely use has commentaries as one of the sources I rely when I am teaching Sunday school. I have found his commentaries to be one of the best and very easy to read.
I enjoy MacArthur's writing style in this series of commentaries. I have his full set of commentaries that I use as one of my sources for studies. I purchased the two commentaries on Acts as a gift for a friend that is preparing to teach a men's bible study. I may not agree with all of his views, but the points and relations to scripture and the history of the times that he brings to light is very much worth reading.
