Time

Time plays a major role in Christian Theology whether we realize it or not. For instance, one of the major reasons the church supports the Trinitarian view is because of time. The thought is that Jesus must have always existed because if he didn't always exist then there must have been a point in time where God thought to create him. However, God exists outside of time, so that cannot be true; ergo Jesus has always existed. There are other theologies that follow similar logic, so the notion of time, and God's existence outside of time, are large players in theology.

Recently, I was reading a book by Gregory Benford called Beyond Infinity. I can't say the book was all that good, but it brought to my attention the thought of multiple time dimensions. Scientists are still postulating what time really is, but there is no reason why there couldn't be multiple dimensions of time just as there are multiple dimensions of space. If that is the case, then there is no reason that God couldn't exist in his own temporal dimension that spawned ours, but still be entirely outside of ours. In that case, the days of Genesis could be completely literal for his time dimension and the idea that a day is like a thousand years could also be taken more literally.

I like the idea of God existing in his own time that is separate from ours. I think it solves a lot of tough theological problems in an elegant manner.
