The point...

...of that last post was basically this: I realize that both viewpoints presented were largely unrelated. The philosophical underpinning of my comments and musings was this: everyone needs a purpose to get behind. Beyond a "spiritual calling" I think that having a purpose, something to fight for, is necessary to living a passionate life.
And here's the thing (where I think Greenpeace has helped me) - the motivation for effecting change is the betterment/improvement/conservation/preservation of one's environment. Whether we are believers fighting for the Kingdom of God or environmentalists fighting for the beauty of the earth, we align ourselves with causes that are meaningful, both intrinsically and which assign our lives deeper meaning.

It is not just the calling of some but really the need of all to become involved with a cause. The causeless are aimless and aimless people are dissatisfied and unfulfilled. Extreme? But I think true.

Does that make more sense?
