38. Verse 18 And to have dominion over the day and the night, and to make a distinction between the light and the darkness; and God saw that it was good.

'The day' is used to mean good, and 'the night' evil. Consequently goods are called 'the works of the day', whereas evils are called 'the works of the night'. 'The light' is used to mean truth, and 'the darkness' falsity, just as the Lord says,

Men preferred darkness rather than light; he who does the truth comes to the light. John 3:19-21.

Verse 19 And there was evening, and there was morning, a fourth day.

1077. The reason the people who are here called 'Ham' and 'Canaan', that is, who separate faith from charity and who in so doing focus worship solely on external things, cannot know what conscience is and where it originates, must be discussed briefly. Conscience is formed by means of the truths of faith, for what a person has heard, acknowledged, and believed constitutes conscience with him. After that, acting contrary to those things is for him acting contrary to conscience, as may become quite clear to anyone. Consequently unless it is the truths of faith that he hears, acknowledges, and believes, he cannot possibly have a true conscience. For it is by means of the truths of faith, with the Lord working within charity, that a person is regenerated, and so by means of them receives conscience. Conscience is also the new person himself. From this it is clear that truths of faith are the means by which this is achieved, that is, by which a person lives according to the things faith teaches, its fundamental teaching being to love the Lord above all things and the neighbour as oneself. If he does not live according to those truths, what is faith but something hollow, and an audible sound, or something separated from heavenly life, in which, once separated, there is nothing saving? For to believe that a person can still be saved no matter how he lives, provided he has faith, is to say that he is saved even though he has no charity and even though he has no conscience. It amounts to saying that, provided he has faith, even though he does not have it until the last hour of life, he can be saved, despite spending his time hating, getting revenge, plundering, and committing adultery, in short, doing everything contrary to charity and conscience. Let such people, when governed by an assumption as false as this, ponder what truth of faith exists that can form their conscience. Will it not be that which is false? If they imagine that they have any conscience at all, it amounts to no more than external restraints - fear of the law, of loss of position, wealth, and reputation on account of these, which fears constitute with them what they call conscience, a conscience which says that they should do no harm to the neighbour but behave well towards him. Since however this is not conscience, because it is not charity, such persons consequently rush into the most wicked and disgusting actions as soon as those restraints have been loosed or done away with. But the situation is altogether different with people who, though asserting that faith alone saves, have nevertheless led charitable lives; for their faith has had charity from the Lord within it.
