Romans 8:22
For we know that the whole creation groaneth and travaileth in pain together until now.
For we know that the whole creation groaneth,.... As a woman with child, ready to bring forth: for it is added,
and travaileth in pain together until now; regeneration is owing to the grace of God, which is compared to "seed", of which men are born again; the means of conveying it is the Gospel, and ministers are the instruments of begetting souls to Christ, and who travail in birth till Christ be formed in them: now the Gospel being carried by the apostles into the Gentile world, and being succeeded there, it was like a woman big with child, ready to bring forth many sons to God; for as it was prophesied, so it came to pass, that "more are the children of the desolate, than the children of the married wife", Isaiah 54:1; and these births were attended with pain. The apostles preached the word with much contention, and the Gentiles received it in much affliction, though with the joy of the Holy Ghost; as a woman rejoices when a man child is brought forth, though the birth has been attended with pain and labour. This was an united groan, and travail of all the converted Gentiles in the several parts of the world, together with the ministers of the Gospel, earnestly desiring more instances of conversion among them; and this vehement desire had appeared "until now", from the first time of the preaching of the Gospel among the Gentiles, to the writing of this epistle; and supposes, that though there were many spiritual births, there were more to come; as there has been, and will be more abundantly, in the latter day: and moreover, this painful labour, and these united groans for spiritual births, the apostles were well acquainted with, and therefore could say, "we know", &c. by their preaching among them, in whom they could easily observe, and do in their writings take notice, how eagerly desirous they were of having the Gospel preached unto them.
