In your belief/opinion:
1. If a tree falls in the forest and no one is around to hear it, does it make a sound?
2. Do you believe in a Spiritual God and/or a Spirit World?
To the first, yes. Why? For the same reason if you were to walk in to a room but no one was there to see you, you would still be present.
To the second, also yes. Why? One need not see some one to know they exist. For example, some people have read the New Testament and have come to believe that Christ exists. They have only read His words but never have they seen him and still, they believe. Here on a forum such as this and many others on the net, we can read the words of many, many different people. More than not, we shall never meet these folks and yet through their words we know that they exist.
As is my way, I am not come here to argue but simply to state what I hold true as best I can. Hopefully my words will resonate with those that choose to read them. If they do, then they will remain written not only here, but upon them as well. If not? No problem.
