Therefore, God is not temporary as the physical is. He is described as 'eternal, immortal, invisible', a 'Spirit' and thus not subject to the same laws of physics which require a material beginning.
Simply quoting something someone once wrote, does not in any way add weight to your argument. It doesn't provide any evidence whatsoever for the existence of a god, let alone any evidence for it being eternal.
To my knowledge, the laws of science have yet to fully investigate the realm of spirit, what makes a person a person, or is responsible for morality. In dealing only with the physically testable and observable is neglected much of what's most important.
"the realm of spirit" - what is that?
"what makes a person a person" - how about a body and a mind?
"morality" - there have been studies on this (and I'll try and find some references). It is also a subject we've discussed quite a lot here.
Love, honor, justice - as Romans 1:20 stated, even the most hardened atheists would recognize those acting in violation of such concepts are doing something 'wrong'
I entirely agree. But it is very simply explained by the fact that we have evolved to follow behaviour that is beneficial to us (as have all other species). When we feel something is "wrong" it is an automatic emotional response to something we recognise as generally being harmful. If we were to feel good about things that were harmful to us, we would be attracted to doing harmful things, and would soon become extinct.
The fact that we understand why things are wrong, and more importantly have an emotional response to things that are right and wrong, which drives our behaviour, is logically compatible with a characteristic that has evolved. It is not logically compatible with "right" and "wrong" being a purely arbitrary notion that has been thrown at us by some other entity.
