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.

Earth" is a general word that can be thought of as a container for other more specific words, as ground, field, or garden. Each of these means a person in an ascending series as that person learns truths from the Bible, thinks about them, and tries to apply them to life. The series represents the way of becoming good and wise. "Earth" and "ground" are terms that can go either way, as in the parable of the sower (Matthew 13:4-8) there was both good ground and bad ground, but "field" and "garden" mean minds that are regenerating towards good. "Earth" in the Bible can mean a person or a group of like-minded people as in a church. But it refers specifically to the external of the person's mind, or of the general thought of the group. If heaven and earth are mentioned together, then both the internals and externals of the mind are meant – something to note when reading the creation story.

In Revelation the word "earth" is used both as a ground level as we use it in its natural sense and also as the sense of a group. The action in this book takes place in the great middle zone of the spiritual world, where people first go and where they are sorted out. There are both evil people and good there, and sometimes at the end of a church the evil can have great influence before a great judgment comes. This level of the spiritual realm is called the "earth" to which the dragon was cast down (Revelation 12:9) and to which the stars fell (Revelation 12:4). The "earth" that swallowed the dragon’s flood means those still-sincere people within the church who discounted the flood of the dragon's falsities (Revelation 12:15).
