• God as everlasting (God moves through time just like we do, but has no beginning or ending) God is described as sempiternal.
• Process Theology (God moves through time with us, and changes).

This idea has been compared to a birdseye view of a highway or road, where you can see the beginning, end and middle all at once. This analogy was suggested by Aquinas when he wrote 'He who sees the whole road from a height sees at once all those travelling on it'.
Time is an aspect of the created world and thus God is in control of…
