We enter the world literally as innocent as babes.
What happens to us, specifically the choices that we make between the womb and the tomb remains a matter of free will.
Your observations on temptations and our personal struggles with them are poignant.
I don’t claim to know all the answers, but I do know what I believe, and all I can do is “each day, try my best, and trust Jesus for the rest.”
I'd say that Original Sin puts a stain on even that.
But even if not, I know that Original Sin has cursed us all with at least a proclivity towards sinful temptations; some folks may have a weakness for the Demon Bottle (perhaps I may have tippled a little, in my own youth), while other folks may suffer from some degree of Same-Sex Attraction Disorder. It wouldn't surprise me if some of these predispositions do manifest genetically; what I object to is the phrase "hard-wired". Wha-huh? Whatever happened to individual choice, to Human Free Will? We're born with individual tendencies, individual weaknesses; but we each choose our own courses of action, throughout the day.
And I say that as a Calvinist myself, so I have no problem with strongly Predestinarian beliefs or thinking; but the extremity of determinism suggested by the advocates of genetic homosexuality is disturbing. For the sake of observing that some of our individual tendencies may have a genetic component, a bit of hereditary weakness or what have you, they'd throw out all the importance of environmental factors, and just plain individual choices, and reduce Human Free Will essentially to the level of the robotic. Now THAT'S the kind of thinking on this subject to which I do object.
Don't know what color you are MK, but I think there must have been an Arminian in the woodpile somewhere ;)
