Of Calvin's many distortions, his most famous was the ridiculous, and fairly Gnostic, idea of "double predestination". That God picked from the beginning the saved and the damned, and that nothing a person did could change their eternal outcome . . . .basically saying our earthly life is meaningless.
Naturally, this idea goes against that of a loving or merciful God.
But is the reality any more evidence of a loving God?
I was thinking of a terrible practice in dog breeding, specifically that of creating Double Merles. This double merle gene breeding can create absolutely beautiful dogs, with the majority of a litter sadly also born blind or deaf or worse (often they are just merely destroyed).
This vile practice of creating a litter in the hopes of keeping one or two reminds me a little too much of how we were made. That God in His infinite intellect decided that it was worth it to Him to create a species that He would inevitably have to destroy, or damn, much of . . . .that He couldn't come up with a better plan and decided to proceed anyway is to me as vulgar as the double merle breeding.
While I am not God, I must say if I had the choice to create a race knowing I would haver to destroy some, vs just not, I would have chosen the latter.
