God is eternal and omniscient. He isn’t bound by time and space; and, unlike man sees all of history like a colossal appointment calendar. Transcending the time space continuum, God has planned every date of the grand calendar of history and knows what He has purposed for each nanosecond. There is a “set time” for every detail of God’s plan and purpose to be fulfilled.
With centuries of visual depictions from which to draw, our imaginations are quick to conjure a romantic picture of the place where God entered time and space.
