buzsaw,
I think you've missed the poeticness of this passage. Do you remember the old tale about a man never crossing the same river twice. He doesn't because there is time in between the past, present, and the future (yesterday, today, and forever). The river has changed and he has changed, so they never meet again.
But God doesn't change, because he's outside of time. He created time, he doesn't experience it. He's at the past, present, and future right now. He's at the day Lincoln was born and the day that he died, and every other time all at the same time. This may be difficult to understand. Here's an analogy:
If you were driving in a car down a road, you would see the road in little chunks of time. If you were in a balloon flying above the road you would see all the road at the same instant. God's in the balloon while we're in the car. We experience the road as connected fragments, but he experiences the whole road. But it's a little more confusing.
The Christian view of God is that he recently became a man, in time on a particular day. So does this make God eternally living in time? Ah, what a question. Theologians would love it. Suffice to say that this is a difficult question. But an answer isn't essential to a Christian view of the world.
