In Genesis 19:37; 21:26; 30:32; 40:7; Matthew 6:30; Luke 12:28, this signifies the perpetuity and eternity of a state. (Arcana Coelestia 2838)

In Psalm 2:7, this signifies in time; for with Jehovah the future is present. (True Christian Religion 101)

The expression 'even to this day' or 'today' sometimes appears in the Word, as in Genesis 19:37-38, 22:14, 26:33, 32:32, 35:20, and 47:26. In a historical sense, these expressions have respect to the time when Moses lived, but in an internal sense, 'this day' and 'today' signify the perpetuity and eternity of a state. 'Day' denotes state, and likewise 'today,' which is the current time. Anything related to time in the world is eternal in heaven, and to represent this, 'today' or 'to this day' is added. Although, in the historical sense, this appears as if the expressions only have a literal meaning, just like it says in other parts of the Word, such as Joshua 4:9, 6:25, 7:20, Judges 1:21, 26, etc. 'Today' means something perpetual and eternal in Psalms 2:7, 119:89-91, Jeremiah 1:5, 10, 18, Deuteronomy 29:9-14, Numbers 28:3, 23, Daniel 8:13, 11:31, 12:11, Exodus 16:4, 19, 20, 23, John 6:31, 32, 49, 50, 58, Matthew 6:11, and Luke 11:3.

7083. Heat and light in the natural world emanate from the sun in the world, whereas spiritual heat and spiritual light, or love and faith, emanate from the sun in heaven. The Lord is the sun in heaven, and the heat which comes from Him as the Sun is love, while the light which comes from Him as the Sun is faith. The fact that the Lord is light is clear in John,

Jesus said, I am the light of the world. He who follows Me will not walk in darkness but will have the light of life. John 8:12.

And the fact that the Lord is a sun is clear in Matthew,

When Jesus was transfigured His face shone like the sun, and His clothes became [white] as the light. Matthew 17:1.
