'Birth' in the Bible

[I went on to say] “We are Jews by birth and not sinners from among the Gentiles;

My little children, for whom I am again in [the pains of] labor until Christ is [completely and permanently] formed within you—

But the child of the slave woman was born according to the flesh and had an ordinary birth, while the son of the free woman was born in fulfillment of the promise.

For it is written [in the Scriptures],“Rejoice, o barren woman who has not given birth;Break forth into a [joyful] shout, you who are not in labor;For the desolate woman has many more childrenThan she who has a husband.”

But as at that time the child [of ordinary birth] born according to the flesh persecuted the son who was born according to [the promise and working of] the Spirit, so it is now also.

For neither is circumcision anything [of any importance], nor uncircumcision, but [only] a new creation [which is the result of a new birth—a spiritual transformation—a new nature in Christ Jesus].
