Tim Keller’s Hermeneutic

Do Keller’s writings provide us with a consistent example of the Reformed hermeneutical method? More specifically, do his interpretations represent the truth that is ‘chiefly taught’ in that place? Does he consistently allow the clearer parts of Scripture to interpret the less clear? And are his deductions from
Scripture ‘good and necessary consequences’? Based on the examples that we have seen, I think the answer would have to be that Keller is not consistent in adhering to these principles.
