Do you believe that G-d ever intervenes in life? I think what we’re getting at here is basic epistemology. Do you believe as the Deists did - that G-d created the world and then left it to run according to the scientific laws that are in effect, and that’s all we have now?
When all the variables are right for conception to occur and yet it doesn’t, would you say there must have been some tiny microscopic thing that wasn’t quite right after all? Or why does it occur sometimes and not others?
“Do you believe that G-d ever intervenes in life?”
I believe G-d does, but I also believe that that is not what G-d does most of the time - intervene, and that most of the time when G-d does intervene few, including those whom G-d is acting upon, realize it; which is why it is arrogant for us, simply when and because our faith is so strong, to declare that G-d has intervened when in fact - most of the time - G-d did not make us aware of that.
I beleive we must be guided by our personal relationship with G-d in these things, not mere theological ideas.
