I have completed my post that goes the the foreword of PFOT in detail: 42: PFOT: The Foreword part 2.
Moreover so far the foreword has done nothing to advance for me the
case of penal substitution nor encourage me to focus on God’s wrath
rather than his love.
It took me much longer than planned to complete that post. Work through the rest of the book will not be in so much detail.
