Sometimes we read things that we disagree with, even from good authors. Here is an example from Chapter 2 of The Mystery of Providence:
Look then, but not proudly, upon your outside and inside. See and admire what Providence has done for you, and how well it has performed the first service that ever it did for you in this world. And yet, this was not all it did for you. Before you saw this world, it preserved you, as well as formed you in the womb, else you had been as those embryos Job speaks of ‘which never saw light’ (3. 16). Abortives go for nothing in the world, and there are multitudes of them. Some never had a reasonable soul breathed into them, but only the rudiments and rough draft of a body; these come not into the account of men, but perish as the beast does. Others die in, or shortly after they come out of the womb, and though their life was but a moment, yet that moment entails an eternity upon them. Had this been your case, as it is the case of millions, then, supposing your salvation, yet you had been utterly unserviceable to God in the world; none had been the better for you, nor you the better for any in the world. You had been utterly incapable of all that good which throughout your life you have either done to others or received from others.
I wonder how Flavel would reconcile the words in bold with Luke 1:39-45?
