Begun To Make - Genesis 2:1-3

Genesis 2:1-3 NETS (Septuagint )

And the heaven and the earth were finished, and all their arrangement. And on the sixth day God finished his works that he had made, and he left off on the seventh day from all his works that he had made. And God blessed the seventh day and hallowed it, because on it he left off from all his works that God had begun to make.

In the Greek translation of the OT we see different wording which implies that God's work was not done in the seven days of creation. The beginning was only the beginning. The end is yet to come. 

Jesus would say later that He and His Father are working even now. 

There is still work to be done before the new creation is fully accomplished.
