AlanF,
Your comments bring up something that I think is very important to religious people -- the desire to have some sort of "higher purpose" in life. I'm not sure that such people really think about why this ought to be important. After all, they have no problem with the notion that animals have no higher purpose, right? Have you really examined the question deeply?
A higher purpose in life? Of course, but seeking a higher purpose is not limited to religious people. Why are you here, AlanF? Isn't it to do some good to help people see the fallacies of the Watchtower and in your opinion of religion itself? You could easily just go about your life spending all your time on yourself and your family but you sacrifice your time to help others or to expose liars. That is a noble thing and a higher purpose, imo. I know that's probably not exactly what you were getting at but I'll respond more directly in minute.
I believe most people are at heart good and if given the chance would certainly live a life which brought themselves and others some joy, some good. Of course mankind has a higher purpose than just to reproduce that goes without saying. We have the capacity to do great and wonderful things beyond childbearing. We create in a myriad of ways, we are for all purposes gods on this planet and we have the capacity to enrich or to destroy it. As for the animals, they have been exploited and many are forced to life miserable lives. They too have a nobler purpose than to merely feed us or enrich multi-national corporations. We can do better towards them much better.
I believe our great capacity to reason, to love, to have compassion, to produce beauty in art, music and architecture, to grow emotionally and mentally, to be what we are, the most powerful and intelligent beings on earth cannot be explained merely by the process of evolution alone. There is a missing piece, a missing element in all this and I believe that missing factor is a Creator. And since I believe that in order to be able to give intelligence this missing element must himself possess intelligence he must then logically also have a purpose just as intelligent human inventors and artistic creators have purpose. Though at present God's purpose may not be clearly understood by many that does not in itself prove he has no purpose and just as human creators can form an emotional attachment to what they have created and would want it preserved, so too God can have an emotional attachment, a love, for his creation and want it preserved. If we have a higher purpose it is to reach our full potential as our Creator would have us do and wants us to do. God's purpose must logically be one which when reached will justify all the work put into it otherwise his purpose will be out of balance with the end result and illogical. A violation of the natural laws around us.
Yes, there is a higher purpose one which reason dictates must exist IF a Creator exists. But that's a big IF for many here, I understand that.
I think that most Christians would answer the question, "What is the purpose of life?" with something like, "To worship, love and honor God." But then, what's the use of that? Other than showing such emotions, such people still do exactly the same thing as people who don't show them do: eat, sleep, reproduce. Can you really give a good answer to the question of why worshiping God is somehow better than just producing children? Please note that to properly answer this, you have to define what you mean by notions like "better".
I don't think that worshipping God is "better" than producing children. My point was that producing children is the bottom line of evolution but the reality is that people have the capacity to do so many beautiful and powerful things beyond simply having children in order to keep the species going. How does the theory of evolution explain that? A belief in a Creator is better able to explain why man is the way he is than evolution. By "better" I mean more complete, less loose ends, simpler, more in tune with logic.
Some feel to honor God they should go to church or preach the Gospel etc., that's all fine but I believe all one needs to do to honor and worship God is to do right by his fellow and by the earth. If the day should come when a man's future hopes for life depended on his knowing God then God would make himself known to him. For now it is not, for now all we are are fellow travelers trying to make sense of things. To me, the symbiosis, beauty, majesty and complexity and simplicity of life on earth leads to the conclusion that we are not alone, to me this makes sense.
