'Creation' in the Bible

We who have believed are soon to be admitted to the true rest; as He has said, "As I swore in My anger, they shall not be admitted to My rest," although God's works had been going on ever since the creation of the world.

But Christ appeared as a High Priest of the blessings that are soon to come by means of the greater and more perfect Tent of worship, a tent which has not been built with hands--that is to say does not belong to this material creation--

In that case Christ would have needed to suffer many times, from the creation of the world onwards; but as a matter of fact He has appeared once for all, at the Close of the Ages, in order to do away with sin by the sacrifice of Himself.
