'Eternal' in the Bible

For our light affliction, which is but for a moment, worketh for us a far more exceeding and eternal weight of glory;

While we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal.

For we know that if our earthly house of this tabernacle were dissolved, we have a building of God, an house not made with hands, eternal in the heavens.
