-- Jn 10:31-42
Jesus asked the religious authorities of Jerusalem to believe in him because of the Father's works which he accomplished. But such an act of faith must go through a mysterious death to self, for a new "birth from above" under the influence of divine grace. Such a demand for conversion in the face of so surprising a fulfillment of the promises allows one to understand the Sanhedrin's tragic misunderstanding of Jesus: they judged that he deserved the death sentence as a blasphemer. The members of the Sanhedrin were thus acting at the same time out of "ignorance" and the "hardness" of their "unbelief".
