I will be lifetime natural, if I can't have with what God gave me, I don't want it
If you accepted nothing but what God gave you (i.e., our species' shared biological heritage), you ought to be content with death by age 40, multitudinous diseases and inborne defects that would kill most of your children, and an inability to engage in any but the most rudimentary thought (probably no mathematics or critical thinking, the sorts of computations that are only possible via the use of external, non-biological devices), among other things.
You've already failed to utilize solely what God gave you to the extent that you utilize modern technology, medicine, and external devices which assist in computations (like the computer you are currently using). This being the case, you might as well violate your principle one more time and utilize PED, because probably God won't care overmuch about how thick your abs are when reviewing your application to Heaven.
