[Gen 3:16, 20 KJV] 16 Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children; and thy desire [shall be] to thy husband, and he shall rule over thee. ... 20 And Adam called his wife's name Eve; because she was the mother of all living.

[Gal 4:26-27 KJV] 26 But Jerusalem which is above is free, which is the mother of us all. 27 For it is written, Rejoice, [thou] barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband.

In sorrow Eve conceives children and is the mother of all living; Jerusalem, the mother of us all, which is above, does it a little differently.

If the heavenly Jerusalem is not the mother of all living, is she the mother of the dead?

[Luk 9:23-24 KJV] 23 And he said to [them] all, If any [man] will come after me, let him deny himself, and take up his cross daily, and follow me. 24 For whosoever will save his life shall lose it: but whosoever will lose his life for my sake, the same shall save it.

[2Co 11:2-3 KJV] 2 For I am jealous over you with godly jealousy: for I have espoused you to one husband, that I may present [you as] a chaste virgin to Christ. 3 But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ.

In sorrow, Eve has her own “children”, with our own husband, which are not of Christ. She is the mother of all living, who do not “lose their life to save it”.

[1Co 7:34 KJV] 34 There is difference [also] between a wife and a virgin. The unmarried woman careth for the things of the Lord, that she may be holy both in body and in spirit: but she that is married careth for the things of the world, how she may please [her] husband.

[Gal 4:30-31 KJV] 30 Nevertheless what saith the scripture? Cast out the bondwoman and her son: for the son of the bondwoman shall not be heir with the son of the freewoman. 31 So then, brethren, we are not children of the bondwoman, but of the free.

[Jhn 8:32-33 KJV] 32 And ye shall know the truth, and the truth shall make you free. 33 They answered him, We be Abraham's seed, and were never in bondage to any man: how sayest thou, Ye shall be made free?

[Jhn 14:16-17 KJV] 16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; 17 [Even] the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.

The Comforter is Christ who formed in you and abides in you.

[Isa 7:14 KJV] 14 Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel.

From Strongs: Immanuel = "God with us" or "with us is God"

So let your unmarried woman conceive of the truth.

[Gal 4:19 KJV] 19 My little children, of whom I travail in birth again until Christ be formed in you,

Paul must have been pregnant with a hidden truth to say something like this.
