'Eternal' in the Bible

And being made perfect, he became the author of eternal salvation unto all them that obey him;

Of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment.

Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.

How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?

And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
