22. Verse 5 And there was evening, and there was morning, the first day.
What 'evening' means, and what 'morning', is recognized from what is said above. 'Evening' means every prior state, because it is a state of shade, that is, of falsity and of absence of faith, while 'morning' is every subsequent state, because it is one of light, that is, of truth and of cognitions of faith. 'Evening' in general means all the things that are man's own, whereas 'morning' means all those that are the Lord's, as is said through David,
The Spirit of Jehovah has spoken within me, and His word is upon my tongue. The God of Israel has said, the Rock of Israel has spoken to me. He is like the morning light, when the sun is rising on a cloudless morning, shining bright, as when after rain tender grass [springs up] from the earth. 2 Samuel 23:4.
Because 'evening' is a time when there is no faith, and 'morning' when there is, the Lord's Coming into the world is called 'the morning', and the time at which He comes, since faith does not exist at that point, is called 'the evening', as in Daniel,
The Holy One said to me, Up to the evening when it is becoming morning, two thousand three hundred times. Daniel 8:13-14.
In the Word, 'morning' stands in a similar way for every coming of the Lord, and so is a term describing the new creation.

571. When anyone is such that he immerses the truths of faith in his own insane desires he renders truths unholy and deprives himself of remnants which, though with him still, cannot be brought out. For the instant they are brought out they in turn are rendered unholy by those things which are already profaned. For profanations of the Word create hard skin so to speak which blocks and absorbs into itself the goods and truths constituting remnants. This being so, let man be on his guard against profaning the Word of the Lord in which eternal truths are present that have life within them, though the person who is under the influence of false assumptions does not believe that they are truths.
