agrote: I love that you question this! No I will not tell you that you don't need proof if you have faith, I have always believed that to be a
HUGE cop out which people use when they can't be bothered coming up with a coherent argument (sorry eoe, no insult intended

). As I said, as far as I'm concerned, faith without reason is not faith, it's fanaticism
The concept of timelessness is a very difficult one, I admit. I've struggled with it for a lot of years. I suppose it really hinges on your concept of what God is. If you think he's just some guy sitting on a cloud arbitraily making up rules for the rest of us then it's really hard to apply the "timeless" thing. Umm, perhaps if I'm going to explain what I mean then I should explain a little about
my concept of God.
My only authority in this matter is a life-time of Catholic indoctrination. Don't get me wrong, I'm not going to start bible bashing, my stance on theology has always been one of inquiry rather than easy acceptance. I don't claim to be a theologian, I've just spent a lot of my time thinking about the things my elders told me.
So what I've come up with so far is that God is more than the common conception of the idea. God is not just a person, or a big powerful thing, God is all. Everything. Everything seen and unseen (hence the statement that God is in all things and all things are in God). That includes us. It includes the past, the future, the whole shebang. So if God is all that is and ever will be, then God is not restricted by time.
This is not the same as the concept of a traveller moving through time (like a time machine), it is time itself. To us it seems like one event after another, immutable, unchangeable. To God, time would be both the procession and the whole at once. (yeah I know I'm just about confusing myself here!)
Let me try an analogy. Think of the entirety of existence as a book. To read the story you start at the beginning and keep going till you get to the end. So you see the story happen piece by piece. But now think of the book as a whole, pretend you hold the book in your hand. The whole story is right there, at one time. The
whole thing. Now say you wrote the book.
So we're the story and God is the author. Time is the turning of the pages. Can you see what I mean?
I hope I have cleared up my statement a little, maybe I just muddied the waters even more. If, indeed, this is the case, I really hope you'll ask again.
