For this people's heart has become gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes and hear with their ears, and should understand with their heart, and should be converted, and I should heal them.
All Commentaries on Matthew 13:15 Go To Matthew 13
Hilary of Poitiers
AD 368
Faith perceives the mysteries of the kingdom. A person will make progress in those things he has been immersed in and will abound with an increase in that progress. But in those things he has not been immersed in, even that which he has shall be taken away from him. In other words, he suffers the loss of the law from the loss of his faith. Lacking faith, the people of the law lost even the efficacy of the law. Therefore, gospel faith receives a perfect gift, because it enriches with new fruit those things that have been undertaken. But once it is rejected, even the help of one’s former means of support is taken away.
