When people pray in the Bible, it means they are opening up their internal states. When it is the Lord praying, or a figure who represents the Lord, that opening up reveals the Lord's inmost love and intention, and means that hidden things will be revealed. When others pray the meaning is less exalted, representing worshiping God from a love of other people.

2580. 'Abraham prayed to God' means a revelation. This is clear from the meaning of 'praying' when it has reference to the Lord, as a revelation being given, dealt with in 2535, and from the representation of 'Abraham' as the Lord, dealt with many times. In the sense of the letter two are portrayed - one who prayed, and another to whom he prayed, for it is said that 'Abraham prayed to God'. But in the internal sense there are not two but one, since it was God or Jehovah within Him - for He was conceived from Jehovah - who made the revelation. Yet insofar as that which constituted the maternal human existed with Him, He was someone other. It is scarcely possible however for an explanation of this to fall into ideas intelligible to man. It can indeed fall into angelic ideas, which are presented in the light of heaven, but it cannot fall so easily into human ideas, which do not perceive anything unless they are illuminated by the things which belong to the light of the world. Still less can such an explanation fall into the ideas of people for whom everything belonging to the light of heaven is thick darkness, so as to be nothing at all.
