Concerning the distinction of a male child and a female child in birth – It is important to recognize that the distinction is not between different individuals (in that one is male and another female), but to indicate the two different statuses of every redeemed individual.
In the spiritual sense, the birth of a male child and its redemption represents the relationship between man and God, his creator. The recovery in this case is seven days, corresponding to the recovery of the first creation. The man is to be redeemed from a fallen state to the sinless Adamic state.
In contrast, the birth of a female child and its redemption represents the relationship between the Church and Christ, her husband. The recovery is therefore two seven days (not 14 days, but double seven days).
The first is the recovery of the first creation, while the second is from the first creation to the new creation. This is the complete salvation. Every child of God is in the position of a female to receive that. This aspect of salvation is also the most lost in today’s church.
