You'll find Kant very good for insomnia. Hume is a good intro and less daunting, at least for me.
I realio trulio hope you will take a look at the first few chapters of Mere Christianity, by C.S. Lewis. I think you would not be bored.
Your distinction between murder and killing is good and important (and too rarely made).
I think in the final analysis every blink of your eye is noted on High (that would be "reverential periphrasis") and God is able to do that, owing to being infinite and all. But I think that, though infinite, God would, if you were the only human ever made, still come and be born and sweat and ache and die for you because He loves you.
I am nothing if not banal.
Thanks again.
Thanks also. I have one further question though, if you do not mind.
Do you think any man, living or dead, with the exception of Jesus, truly knows the nature of God?
