There being then a twofold species of vice--that characterized by craft and stealth, and that which leads and drives with violence--the divine Word cries, calling all together; knowing perfectly well those that will not obey; notwithstanding then since to obey or not is in our own power, provided we have not the excuse of ignorance to adduce. He makes a just call, and demands of each according to his strength. For some are able as well as willing, having reached this point through practice and being purified; while others, if they are not yet able, already have the will. Now to will is the act of the soul, but to do is not without the body. Nor are actions estimated by their issue alone; but they are judged also according to the element of free choice in each,--if he chose easily, if he repented of his sins, if he reflected on his failures and repented (μετέγνω), which is (μετὰ ταῦτα ἔγνω) “afterwards knew.” For repentance is a tardy knowledge, and primitive innocence is knowledge. Repentance, then, is an effect of faith. For unless a man believe that to which he was addicted to be sin, he will not abandon it; and if he do not believe punishment to be impending over the transgressor, and salvation to be the portion of him who lives according to the commandments, he will not reform. Hope, too, is based on faith. Accordingly the followers of Basilides define faith to be, the assent of the soul to any of those things, that do not affect the senses through not being present. And hope is the expectation of the possession of good. Necessarily, then, is expectation founded on faith. Now he is faithful who keeps inviolably what is entrusted to him; and we are entrusted with the utterances respecting God and the divine words, the commands along with the execution of the injunctions. This is the faithful servant, who is praised by the Lord. And when it is said, “God is faithful,” it is intimated that He is worthy to be believed when declaring aught. Now His Word declares; and “God” Himself is “faithful.”[59] How, then, if to believe is to suppose, do the philosophers think that what proceeds from themselves is sure? For the voluntary assent to a preceding demonstration is not supposition, but it is assent to something sure. Who is more powerful than God? Now unbelief is the feeble negative supposition of one opposed to Him; as incredulity is a condition which admits faith with difficulty. Faith is the voluntary supposition and anticipation of pre-comprehension. Expectation is an opinion about the future, and expectation about other things is opinion about uncertainty. Confidence is a strong judgment about a thing. Wherefore we believe Him in whom we have confidence unto divine glory and salvation. And we confide in Him, who is God alone, whom we know, that those things nobly promised to us, and for this end benevolently created and bestowed by Him on us, will not fail.
