The other day I was reading in my book by Francis Chan, Crazy Love, and something I've wondered about for a long time somewhat started to make since to me. Some of us wonder just how long eternity is, and some of us have accepted the fact that we can't understand it at this point in time, and never really will. I've always wondered why we couldn't really fathom the word "eternal."
In his book Francis Chan describes it like this. God was before time, and he created time, so he has power over time itself. We, humans, were created IN time. God was there even before time existed, so if God doesn't exist "in time" but we do, then we couldn't possibly contemplate what forever feels like. And only those "in Jesus" who is "out of time" will ever know how long forever and eternity really is :)
