'Renewing' in the Bible

And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.

Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;

for this [first or outer tabernacle] is a symbol [that is, an archetype or paradigm] for the present time. Accordingly both gifts and sacrifices are offered which are incapable of perfecting the conscience and renewing the [inner self of the] worshiper.
