Ezekiel 28 reveals that Satan's fate will be ashes in the Lake of Fire; it would be inconsistent with God's character for Him to inflict pain eternally.
Jesus magnified the Sabbath, giving principles by which to judge our activities. Each time Jesus taught about the Sabbath, He emphasized some form of redemption.
