This was a symbol for the time then present, when gifts and sacrifices were offered that could not perfect the conscience of the worshiper.

For it was fitting for him, for whom and through whom all things exist, in bringing many sons to glory, to make the pioneer of their salvation perfect through sufferings.

For the law possesses a shadow of the good things to come but not the reality itself, and is therefore completely unable, by the same sacrifices offered continually, year after year, to perfect those who come to worship.
