Faith # 54
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).
Heaven and Hell # 126
126. Light and Warmth in Heaven
People who think solely on the basis of nature cannot grasp the fact that there is light in the heavens; yet in the heavens there is so much light that it is vastly greater than noonday light on earth. I have seen it often, even during our evenings and nights. At first I was amazed when I heard angels saying that our world's light was nothing but shadow in comparison to heaven's light, but now that I have seen it, I myself can bear witness. Its brightness and brilliance are beyond description. What I have seen in heaven I have seen in that light, and therefore more clearly and distinctly than what I have seen in this world.
