Wine played a key role in the ancient world, where safe, reliable water sources were scarce. It could be stored for long periods of time; if lightly fermented it was rich in sugar content; it was high in mineral content; it tasted good and generally had intoxicating qualities. Thus it was a valuable commodity and treated with reverence.

Wine is, of course, made from grapes. Grapes – sweet, juicy, nutritious and full of energy-rich fructose – represent the Lord's own exquisite desire to be good to us. That's powerful stuff! But grapes have a short shelf life; you might eat a bunch for a burst of energy, but you can't exactly carry them around with you for long-term sustenance. And so it is with desires for good: They tend to come to us in energizing bursts, but fade away fairly quickly. We need something more stable and lasting.

At some point in the distant past people figured out that if you squeeze the juice from the grapes and let it ferment, the result is a liquid that offers that stability: wine. The spiritual meaning works the same way; if we examine our desires for good, try to understand and think about how to apply them, what we will get are concepts about what good really is, how to recognize it and how to make it happen. And just like the wine, these ideas offer stability and portability. For instance, finding a wallet full of cash on the sidewalk might severely test our desire to be honest, but the idea that "you shall not steal" is pretty hard to shake.

Wine, then, on the deepest level represents divine truth flowing from divine goodness – the true principles that arise from the fact that the Lord loves us and desires everything good for us.

Wine comes in many varieties, though, and is used in many ways. Depending on context it can represent truth that arises from a desire for good on much more mundane levels. You want your children to be healthy so you make them brush their teeth even though they complain and it's a pain in the neck; the truth that brushing their teeth is good for them is wine on a very day-to-day level.

In some cases wine can also actually represent good things that arise from true ideas, something of a reverse from its inmost meaning. This happens when we are in transitional stages, setting higher ideas and principles above our less-worthy desires in an effort to reshape our actions. In that case our principles are the things being squeezed, with good habits the result.

There is also, of course, a darker side to wine. There is a good deal of debate about just how much alcohol wine had in Biblical times, and some of it may indeed have been more like concentrated grape juice. But there are also many references to wine and drunkeness, so some of it, at least, was fairly potent.

On a spiritual level, getting drunk on wine represents relying too much on our ideas, taking logic to such an extreme that we forget the good things we were trying to achieve in the first place.

233. Investigating mysteries of faith by means of facts is as impossible as it is for a camel to go through the eye of a needle, or for a rib to control the tiniest fibres of the chest and the heart. Just as gross, indeed far more gross, is what is sensory and factual in comparison with what is spiritual and celestial. Anyone who wishes to probe merely the secrets of nature, which are countless, discovers scarcely a single one, and when he starts to probe he sinks, as is well known, into falsities. What then would happen if he wished to probe the secrets of spiritual and celestial life, where thousands and thousands of secrets exist for each one contained in the unseen parts of nature?

[2] To illustrate the point, let just one example be taken. Of himself man is incapable of anything other than doing evil and turning himself away from the Lord. Yet it is not the man who does so but the evil spirits residing with him. Yet again it is not the evil spirits who do it but the evil itself which they have made their own. All the same, man does that evil and turns himself away, and is blameworthy, even though his life comes from the Lord alone. On the other hand man of himself cannot possibly do good and return to the Lord. This is accomplished by angels. Yet the angels cannot do it, but only the Lord. All the same, man is capable as if of himself of doing good and of returning to the Lord. The truth of all this cannot possibly be grasped by the senses, formulated knowledge, or philosophy. If these are consulted they deny those things outright, even though they are inherently true. And the same applies with everything else.

[3] These considerations show that people who consult sensory evidence and factual knowledge in matters of belief plunge themselves not only into doubt but also into denial, that is, into thick darkness. And in plunging into thick darkness they also become immersed in every kind of evil desire, for in believing what is false they also do what is false. And when they believe that the spiritual and the celestial do not exist they believe that only the bodily and the worldly do so. So they love anything that belongs to self and the world, and this is how evil desires and evils themselves arise out of what is false.
