John Chrysostom

"For my counsels are not as your counsels." … Now if we admit to our favor household slaves when they have offended against us, on their promising to become better, and place them again in their former position and sometimes even grant them greater freedom of speech than before, much more does God act thus. For if God had made us in order to punish us, we might well have despaired and questioned the possibility of our own salvation. But if he created us for no other reason than his own good will, and with a view to our enjoying everlasting blessings, and if he does and contrives everything for this end, from the first day until the present time, what is there which can ever cause us to doubt? Have we provoked him severely, in a way no other person did? This is just the reason why we ought specially to abstain from our present deeds and to repent for the past and exhibit a great change. For the evils we have once perpetrated cannot provoke him so much as our being unwilling to make any change in the future. For to sin may be a merely human failing, but to continue in the same sin ceases to be human and becomes altogether devilish.
