I think you may have misread me on perfection, a thing I don't believe we have the capacity to attain, though a thing present in God, who is perfect in every particular. I suspect the notion of self perfection of will is one of the most alluring snares of ego and tool of the enemy.
Yes, I agree with you on both counts. One of the great advantages to believing in "God" is that for most people, "God" embodies the ideal of perfection. And as such becomes that "lighthouse; to steer the course of our lives, by" (quoting myself :chuckle: ). I know that for myself, and for many other folks I know, this characteristic of the god-ideal has been a great asset to the quality of my/our life, behavior, and being.
And I agree, too, that the illusion that one can achieve perfection (or even worse, HAS achieved it), oneself, is an open door to a kind of ego-centric insanity that can blossom into all manner of mayhem!
As to our desires...good is nothing without a context, just as a killing becomes murder or something else by that same understanding. So we can serve a beneficial purpose within a particular need, but the good will elude us, even as the benefit inures us to believing ourselves its maker.
For me, the context is existence, itself.
It is a presupposition of mine that it's better to be, than not to be. And as my consciousness expands with maturity, that presupposition applies to an ever-increasing and inclusive grasp of 'being'. Not just mine, and yours, but ALL being. And this underpins that universal "goodness" that I was referring to: that it is better to create and maintain than to destroy. That the "good" is served by serving the continuance of 'universal being', while "evil" is served by the destruction/dissolution of same.
For me, the term "God" refers to that 'universal being', of which you and I and all things are a part. So to serve "God" is to serve the creation and maintenance of universal being. While to serve "evil" is to seek the destruction of same.
I think we basically agree, I'm just putting your somewhat religious terminology into my somewhat 'universalist' (taoist) terminology.
