Creation happens anew every day, from nothing to the fullness of that which is, just as it occurred in the beginning,
So that it is not a single action.
Nor is it a continuous (evolutionary) process.
It is an ongoing renewal of creation each day and all the time.
That is to say, at every point in time there is a new creation of the world.
Like the heartbeat of life. If the pulsation should cease for any reason, all life comes to an end.
In this sense, there is an oscillation of the creation of the world.
At every moment in time it is renewed.
There is no existence without the creative force that continues to fashion all that has come out of nothing.
