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.

368. 'A field' means doctrine, and so everything constituting doctrine concerning faith and charity. This is clear from the Word. In Jeremiah,

O My mountain in the field, I will give for spoil your resources, all your treasures. Jeremiah 17:3.

Here 'field' stands for doctrine, 'resources and treasures' for the spiritual riches of faith, that is, the things that constitute the doctrine of faith. In the same prophet,

Surely the snow of Lebanon will not leave the rock of My field? Jeremiah 18:14.

In reference to Zion it is said, in Jeremiah 26:18; Micah 3:12, that 'it will be ploughed up like a field' when the doctrine of faith does not exist. In Ezekiel,

He took from the seed of the land and planted it in a seed field. Ezekiel 17:5.

This refers to the Church and her faith, for doctrine is called 'a field' because of the seed it has in it. In the same prophet,

And let all the trees of the field know that I, Jehovah, will bring low the high tree. Ezekiel 17:24.

In Joel,

The field has been laid waste, the ground has been mourning because the corn has been laid waste, the new wine has failed, the oil has fallen off. Farmers have been put to shame, the harvest of the field has perished, all the trees of the field have withered. Joel 1:10-12.

Here 'field' stands for doctrine, 'trees' for cognitions, 'farmers' for people who cultivate them. In David,

The field will be exultant and everything in it; then all the trees of the wood will sing. Psalms 96:12.

Here it cannot be a field that is exultant nor trees of the wood that sing, but things residing with man, namely cognitions of faith. In Jeremiah,

How long will the land mourn, and the grass of every field wither? Jeremiah 12:4.

Here similarly it cannot be the land nor the grass of the field that mourns but something with man that has been laid waste. Similarly in Isaiah,

The mountains and hills will resound before you with song, and all the trees of the field will clap their hands. Isaiah 55:12.

The Lord too, when foretelling the close of the age, also calls the doctrine of faith 'a field',

Two will be in the field, one will be taken, the other left. Matthew 24:40; Luke 17:36.

'Field' is used to mean the doctrine of faith, false doctrine as well as true, as in the present verse in Genesis. Because 'field' means doctrine anyone receiving any seed of faith, whether the individual, the Church, or the world, is called a field.
