There is the age of the law, and the age to come, that is, the age of the Messiah. The Jews believed there would be much more grace in the last, and in a sense they were right. (At present, all is in suspense as to the ages: we are heavenly.) Those who blasphemed against the Spirit, even under the Messiah, should not be pardoned. They owned that Christ cast out demons; they owned the acts of power; thus they sinned with deliberate knowledge. If they had said that it was imposture, there might have been pardon for them.
