I just read all 7 pages from beginning to end (whew!!!). While I'm intimidated by the incredible knowledge and deep thoughts of many of you, I'm going to go ahead and throw in my 2 cents (two coins of very little value).
It seems to me that all of this discussion revolves around what existed at the beginning?
The premise is that God has no beginning, while all other things do have a beginning. Everything we know has a beginning and end. Without a beginning and an end, our lives are quite meaningless and without point.
We tend to associate all "things" with this linear type of thinking. That's all I'm personally capable of.
So if all "things" and time have a beginning but God does not, then at some point there was only God existing in a vacuum alone (whether part of a triune godhead or not). So that begs the questions why did he see the need to create anything? What did he create these things out of? It also lends credence to the OP's original musings of His relative knowledge, love, wisdom, and power.
If God has a beginning, then who began Him?
I'm not sure our brains are capable of conceiving beyond the rational linear thinking, putting aside concepts of beginning and end.
There are so many implications to these ponderings. If God does exist and had no beginning then created the vast universe and created life on this tiny speck of a planet, why would we conclude that we are anything more than a "hobby" a form of entertainment to God or an experiment? I liken it to a scientist who starts out with a hypothesis and then begins an experiment with various control samples and variables and seeks answers. His premise in the beginning is a desire to succeed but expects failure. Its from these failures that he takes notes and makes improvements. The aim is to gain as much knowledge as possible, to amass information. Perhaps that all we are to God. He steps away to observe how other experiments and studies are doing and then check back from time-to-time, adding different variables to the equation to see what will happen. I could see us as nothing more than a source of entertainment and an experimant, perhaps not the first of this kind.
On the otherhand, if God does not exist, the ponderings are truly beyond grasp yet they are also without limitation, making anything eventually possible and humans as potential masters of the universe as the only known thinking and devising creatures with an actual concept of time.
I hope I'm not off topic, I kind of get on a run and tyoe and think at the same time. Be gentle in your replies, I'm truly a babe in scientific matters and philosophy as well. But this topic so intrigues me I don't want it to end.
