Time is an illusion. "'Today' is the day of salvation." There is only one day, his day, his time, his story (history). Matter is energy (from God), from which the creation of time, space, and matter came into being. God has projected (as with light/energy) the imagery of his story, for the telling of it.
Your day, your father's day, Jesus' day...they are the same day, but each its own, like parallel universes. Time is an illusion: We enter into our day in our own time, we exit in our own time, but we come into the timeless eternity of God simultaneously. History tells the story on a timeline...just as we often put something that is one matter, together from many pieces...even though it is only one thing. Collectively, all of our "times" have but one purpose: salvation, the rescue of the good of God's creation prior to rebellion. When the last soul is rescued, God will close the book on his story and unplug the power...after all, "It is finished" already.
As for God's place in the world: He sent his Christ (God in the flesh) to save the lost. His work is complete. Time and salvation, and the pages of the story, simply continue until the end of the story, until are who are his are saved.
