7384. 'And cause frogs to rise up onto the land of Egypt' means reasonings arising from utter falsities. This is clear from the meaning of 'frogs' as reasonings arising from utter falsities, dealt with in 7351, 7352. Frogs also correspond to reasonings arising from falsities, for all things without exception in the natural world have a correspondence with those in the spiritual world; and the reason for this is that what is natural comes into existence through what is spiritual. The whole natural system is therefore a theatre representative of the spiritual world, 2758, 3487, 4939.

3487. The words which come before these and which were explained in 3353-3356 are a description of the first state of the perversion of the Church - a state when people will cease to know any longer what goodness is and what truth is, and will start to argue with one another about these, with the result that falsities arise. The words in the present section however describe the second state of the perversion of the Church - a state when people will treat goodness and truth with contempt and will also loathe them, so that faith in the Lord will breathe its last, doing so by degrees as charity comes to an end.
