This is a fairly terrible commentary. It is very well written (as in, easy to read), but it lacks substance. It's also sprinkled with misinformation that lacks references. For example, the section on Gal 3:13-14 says: "the Jews customarily executed people by stoning, probably to avoid the special curse that rested, under the Law, upon those who were hanged." The author is referring to Deut 21:22, but has misread the text. Those verses speak of someone who is put to death and then hung on a tree. This seems to mostly be an opinion piece rather than a scholarly commentary. Rather than exegete the text, the author spouts doctrine that he fails to connect to the text. He rails against the Law for extended sections. I believe the author has missed the point of the Law. He says: "Paul now explains the purpose of God’s law. It has two chief functions: first, to probe the soul for sin, and second, to prepare the soul for salvation." But salvation is not the goal; it is the means to the goal. The goal is God dwelling with His people, and the people fellowshipping with God. The Law did that by means of the tabernacle, although the law was limited because of the flesh (Romans 8:3). I recommend avoiding this commentary.
