(e) You can also see the infinity of God the Creator in the infinite number of stars, which are all suns, and all have solar systems. Elsewhere, in a short work that I wrote as an eyewitness, I have shown that out in space there are planets that have people, animals, birds, and plants.
(f) The angelic heaven and also hell have made the infinity of God even more obvious to me. God has arranged and ordered both places into countless communities and groups according to every type of love for good or love for evil, allotting every individual a location according to what she or he loves. All members of the human race have gathered there since the creation of the world; they will continue to gather there throughout the ages of ages. Although each person has his or her own place and situation, still all who are there have such a partnership with each other that the entire angelic heaven is like one divine human being, and the entirety of hell is like one monstrous devil. From the entirety of heaven and the entirety of hell and from the infinite number of astounding things in them, both the immensity and the omnipotence of God stand in plain view.
(g) If we raise the level of our mental reasoning a little, surely we can all understand that the life to eternity we will all have after death is impossible unless God is eternal.
(h) There are further aspects of infinity that become visible to us, some in physical light and others in spiritual light. As examples that become visible in physical light, there are various geometrical series that go on to infinity. On each of the three vertical levels as well, there is a progression to infinity. The first level, called the earthly level, cannot be refined and raised to the perfection of the second level, called the spiritual level. Neither can this level be refined and raised to the perfection of the third level, called the heavenly level. It is like the purpose, the means, and the result. No matter how developed the result becomes, it cannot take the place of the means to itself; nor can these means take the place of the purpose behind them.
Take the three levels of atmospheres as another illustration. The aura is supreme, the ether is below it, and the air is under the ether. No type of air can ever have such high quality that it becomes a type of ether, nor can any type of ether ever have such high quality that it becomes a type of aura. Yet the qualities of each of these atmospheres can be developed and improved to infinity.
As for examples that become visible in spiritual light, the earthly type of love an animal has cannot have such a high quality that it becomes the spiritual love that creation has endowed us with. Likewise an animal’s earthly intelligence cannot have such a high quality that it becomes human, spiritual intelligence. Because these last points are not yet known, they will be explained elsewhere [Sections 48:8–15; 335].
From all the above examples you can see that features that are universal to our world are everlasting tokens of God the Creator’s infinity. As for the way specific things imitate those universal features, however, and reflect the infinity of God, this is an abyss; it is an ocean the human mind can navigate, as long as it remains watchful for storms arising from the earthly self that would sink the ship—masts, sails, and all—starting with the helm where the earthly self stands confident.
