God appointed by the law the fountains of all good things to be under the principles of generation itself. And what I mean is something of this sort. A little while before he appointed mercy and pardon to exist, now again he decrees that penitence shall exist, not in any degree mocking or reproaching these men, who are believed to have offended, and at the same time giving the soul an opportunity to mount up from wickedness to virtue, like the conversion of those who are proceeding towards a snare.
For behold, the man being made a husband and a father together with his birth, makes a beginning of honesty. And he is said to please God, for although he does not persevere in piety from the moment that he is born, nevertheless, all that remaining period is counted to him as having been spent in a praiseworthy mode of life, because he pleased God for so many years. And these things are said, not because it perhaps was, but it might perhaps have seemed different; but he approves of the order of things, for indulgence having been exemplified, in this case of Cain, after no long interval of time, he introduces this statement, that Enoch practised repentance, warning us by it that repentance alone can procure indulgence.
