John Chrysostom

For all are not alike fit for all things; these are of pure life, but have not so great faith; those again have the reverse. Therefore God converted these by the means of those to the shewing forth much faith; and those that had faith He called by this unspeakable gift of miracles to a better life; and to that end gave them this grace in great richness. And they say, We have done many mighty works. But because they were ungrateful towards those who thus honoured them, it follows rightly, Then will I confess unto you, I never knew you.
