There is, for everyone, a crossroads when it comes to spiritual things, a basic decision to be made. Are you going to believe in the Lord and in spiritual reality? Or are you only going to believe what you can see, touch, feel and otherwise "know" from your own mind? The Writings say those who choose the latter course are closing themselves off from the truth, because by definition spiritual reality cannot be seen, touched, felt or otherwise "known" through purely human means. That's what it means to eat "of the tree of the knowledge of good and evil," and it leads to spiritual death – which is being cut off from the goodness and truth the Lord wishes to bestow on us.

The people of the Most Ancient Church were in a state of love to the Lord, and had been invited to gather all the wisdom and knowledge flowing from that love – the fruit of all the other trees. But they had to accept the Lord as the source, had to accept that He existed, had to accept that He was infinite and beyond their finite understanding. To think otherwise – to think that through their own minds they could explain the Lord – would be to put themselves above him, and lead them into evil.

It's worth noting that this was not a call for people to shut down their minds. The fruit of the other trees represents an incredible bounty of exploration, learning and wonderment. And we're not called on to shut down our minds today; the Lord gave us our intellectual faculties for a reason. To let the Lord in, though, we have to accept the unprove-able idea that He is love itself and reality itself, and see all other knowledge in that light.

3643. It was observed that they who are in the heavens are in a serene aura of light, like the light of morning and of noon, also verging to evening; and in like manner that they are in heat as of spring, of summer, and of autumn; whereas they who are in hell are in an atmosphere gross, cloudy, and dark, and are also in cold. It was observed that between these in general there is an equilibrium; also that in proportion as the angels are in love, charity, and the derivative faith, in the same proportion they are in an aura of light and of vernal heat; and in proportion as the infernals are in hatred, and thence in falsity, in the same proportion they are in thick darkness and in cold. As before said in the other life the light has intelligence within it, the heat has within it love, the thick darkness insanity, and the cold hatred.
