For what it was it was decent. For the level of readership and study it was intended for I would much more encourage people to read either Grudem's commentary in the TNTC series, Sanchez's in the Good Book Company series called 1 Peter For You, or RC Sproul's. Each of those have their own merit but I think are much more substantial and driven by the text. Sanchez's would be the closest to it as far as having more application than Sproul or Grudem. But Sproul and Grudem aren't much more difficult to read. At any rate, I would recommend all three of those before recommending Adams.
