I read this somewhere recently ;)
it may help as a way of explaining what I'm talking about.
take a piece of paper and fold it in half. Push a pencil through the paper making two holes. Then unfold the paper.
the space between the two holes can be portrayed is our "time"...the two holes can portray the Son...the beginning and the end. in this way it can be demonstrated how the Son can be creator of our "time" and be the pre-existant One as well as exist in our "time"...Jesus...Immanuel...God with us.
