A "field" in the Bible usually represents the Lord's church, and more specifically the desire for good within the church. It's where good things start, take root, and grow. When you have a desire to be a good person and to do good things, the natural first questions are "What does that mean?", "What should I do?", "What can I do?". You look for ideas, concepts, direction. Once you figure out something you want to do or a change you want to make in yourself, you seek specific knowledge. If you want to volunteer at a food pantry, say, you'd need to know whom to call, when they need help, where to go, what to bring. Armed with that knowhow, you're ready to get to work. That process could be compared to food production. You start with a field -- which is that desire to be good. Then you plant seeds -- those ideas and concepts. Those seeds sprout into plants -- the specific facts and knowledge needed for the task (easily seen in the food pantry example, but also true with deeper tasks like "being more tolerant of my co-workers" or "taking more time for prayer," or "consciously being a more loving spouse"). Finally, those plants produce food -- the actual good thing that you go and do. The Writings also say that in a number of cases a "field" represents the doctrine, or teachings, of the church. This sounds markedly different. The desire for good is emotional, a drive, a wanting; doctrine is a set of ideas. But for a church to be true, its doctrine must be centered on a desire for good, and must lead people toward doing what is good. So sound doctrine is actually closely bound up with the desire for good.

3069. 'And I will drink' means instruction from them in truth. This is clear from the meaning of 'drinking' as receiving instruction. References to 'drinking' occur in various places in the Word, and whenever the subject is the goods and truths of faith, instruction in these and reception of them is meant, as in Isaiah,

The new wine will mourn, the vine will languish, all the merry-hearted will sigh; they will not drink wine with singing, strong drink will be bitter to those drinking it. Isaiah 24:7, 9.

'Not drinking wine with singing' stands for not receiving instruction from the affection for truth and not receiving any consequent delight. 'Strong drink being bitter to those drinking it' stands for repugnance. In the same prophet,

It will be as when a thirsting man dreams, and behold, he is drinking; and he awakes, and behold, he is faint, and the soul is craving. Isaiah 29:8.

'Thirsting' stands for desiring instruction, 'drinking' for receiving it, but in things that are valueless.

[2] In Jeremiah,

Our waters we drink for silver, our timbers come for a price. Lamentations 5:4.

'Drinking waters for silver' stands for receiving instruction but not for nothing, and also attributing truth to oneself. Truth is a free gift and so does not come from oneself but from the Lord, as these words in Isaiah declare,

Everyone who thirsts, come to the waters, and he who has no money, come, buy! Isaiah 55:1.

And in John,

Jesus said, If anyone thirsts let him come to Me and drink. Whoever believes in Me, out of his belly will flow rivers of living water. John 7:37-38.

Here 'drinking' means being given instruction and accepting it. In Luke,

They will say, We ate in Your presence and we drank, and You taught in our streets. But the Lord will say, I do not know where you come from; depart from Me, all you workers of iniquity! Luke 13:26-27.

Here 'eating and drinking in the Lord's presence' stands for giving instruction in, and proclaiming, the good and truth of faith, doing so from cognitions drawn from the Word, which is meant by 'You taught in our streets'. But because they did it for selfish reasons - for the sake of personal honour and gain, thus not out of any affection for good and truth, and so possessed cognitions of truth and yet led evil lives - it is said, 'I do not know where you come from; depart from Me, all you workers of iniquity!'

[3] In the same gospel, where Jesus was talking to the disciples,

That you may eat and drink at My table in My kingdom. Luke 22:30.

It is evident to anyone that in the Lord's kingdom they do not eat and drink, and that no table is there, thus that something different is meant by 'eating and drinking at the Lord's table in His kingdom', that is to say, enjoying a perception of good and truth. So also with what the Lord says in Matthew,

I tell you that I shall not drink from now on of this fruit of the vine until that day when I drink it [new] with you in My Father's kingdom. Matthew 26:28, 29.

'Drinking' stands for giving living instruction in truths and imparting a perception of good and truth. That which the Lord said -

Do not be anxious for your soul, what you are going to eat or what you are going to drink, nor for your body, what you are going to put on. Matthew 6:25, 31; Luke 12:29 - is indicative of spiritual things, that so far as all things of faith are concerned, goodness and truth are imparted by the Lord. In John,

Jesus said to the Samaritan woman, Everyone who drinks of this water will thirst again, but he who drinks from the water that I shall give him will never thirst. But the water that I shall give him will become in him a spring of water leaping up into eternal life. John 4:7-14. 'Drinking' clearly stands for being given instruction in goods and truths, and the acceptance of them.
