54. We can see from the following passages that circumcision represented purification from evils that are caused by strictly earthly love:

Circumcise your heart and take away the foreskin of your heart, so that my wrath will not break forth because of the ill will of your deeds. (Jeremiah 4:4)

Circumcise the foreskin of your heart and no longer stiffen your neck. (Deuteronomy 10:16)

To circumcise the heart or the foreskin of the heart is to purify ourselves from evils.

Conversely, then, being uncircumcised or having a foreskin refers to people who have not been purified from evils caused by strictly earthly love and who are therefore not devoted to caring, and since having a foreskin means being unclean at heart, it says that no one who is uncircumcised at heart or uncircumcised in the flesh is to enter the sanctuary (Ezekiel 44:9); that no uncircumcised person is to eat the Passover meal (Exodus 12:48); and that the uncircumcised are damned (Ezekiel 28:10; 31:18; 32:19).

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.
