There is a lot that this review gets right about JBP. It gets clear the deficiencies of his Christian profession from a conservative Christian perspective as well as the works righteousness of his program.
If there is anything the piece fails at it is the opportunity missiologically of this moment and I think perhaps the opportunity of the contribution for Peterson to contribute exegetically.
I realize that second point will raise the most questions because at least on my reading Peterson from a grammatical/historical perspective does get a lot of things wrong in his telling of scripture. He’s a complete novice in that discipline. I think he does help open up a symbolic interpretation of some passages which many from my tradition haven’t paid sufficient interest or intention to but there is perhaps more he is uncovering from a perspective of organic inspiration. I say perhaps because my thinking on this is way too new and immature.
