Are you a good person?
Where do you get logic absent God?
Are you arguing for the existence of god now, or are you arguing for free will? The way I see it one can't exclude the possiblity that something like god exists, but at the same time free will doesn't exists.
But okay, since I might not get the opportunity so soon again, I'll entertain your questions anyway:
Where do you get logic absent God?
Logic simply is. At least according to Craig's interpretation of christianity, god isn't beyond logic either, meaning god hasn't created logic, and god is governed by the laws of logic just as humans are. God can't do anything that's logically impossible. Why should it be any different for his creation?
Are you a good person?
Not sure if this is a personal question or just a stepping stone in your argument. But in any case, let me answer with a personal touch: Who cares if I'm good or bad, or if anyone is good or bad for that matter, if you actually believe that the majority of people will suffer terribly for all eternity after death? The purpose of being good the way I see it, is to limit suffering. If you believe there's actually an infinite amount of suffering in store for most people well... Let's just say I wouldn't give a damn about the existence of objective morality anymore. I'd much rather live in a world devoid of even subjective morality, where people bash each other's heads in, as long as it's just over once you bite the dust,
With that in mind, I find the way that Craig stresses his moral argument quite ridiculous: Oh No! God must exist, because otherwise what about muh objective morality?? How terrible the world would be!!

No offense, but from what you've written here, I can't really determine if you've actually read what I've written. What exactly is your refutation to Strawson's argument? With which step of the argument do you disagree?
