129. Anybody can recognize that the basic assumptions a person makes, even when completely false, govern him, and that all knowledge and reasoning buttress those assumptions. For countless flattering ideas occur to him to confirm him in falsities. Consequently when a person's basic assumption is to believe nothing until he sees and understands it, he cannot possibly believe; for spiritual and celestial things are neither visible to the eyes nor comprehensible in mental images. But the true order is for a person to become wise from the Lord, that is, from His Word. In that case everything follows as it should, and he is also enlightened in matters of reason and of fact. Indeed nobody is forbidden to acquire knowledge, since it is useful for life and gives delight. And the person in whom faith resides is in no way forbidden to think and to talk as learned people in the world do. But he does so from the premise of belief in the Lord's Word and of confirming spiritual and celestial truths by means of natural truths, using as far as is possible the terminology of the learned world. Consequently his premise must be the Lord, not self; the former is life, while the latter is death.

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.
