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.

3038. 'To your seed I will give this land' means the Divine Truth which belonged to the Lord's Human. This is clear from the meaning of 'seed' as the faith that is an expression of charity, and also those in whom such faith is present, dealt with in 1025, 1447, 1610, 2848 (and since all good and truth of faith are received from the Lord, it is Divine Truth itself that is meant in the highest sense by 'seed'); and from the meaning of 'this land', namely Canaan, as heaven or the Lord's kingdom, dealt with in 1413, 1437, 1607. And as heaven or the Lord's kingdom is meant, it is the Lord's Divine Human itself that 'the land of Canaan' is used to mean in the highest sense. For the Divine itself cannot flow into heaven except through the Lord's Divine Human, which the Lord also made plain in Matthew,

All things have been delivered to Me by My Father; and no one knows the Son except the Father, nor does anyone know the Father except the Son and he to whom the Son wishes to reveal Him. Matthew 11:27.

And in John,

Nobody has ever seen God; the only begotten Son who is in the bosom of the Father, He has made Him known. John 1:18.

'The Son' is the Lord's Divine Human. Anyone who believes that in heaven they worship any other Father than the Lord is much mistaken.
