'Eternal' in the Bible

For in this way, entry into the eternal kingdom of our Lord and Savior Jesus Christ will be richly supplied to you.

And in their greed they will exploit you with false arguments and twisted doctrine. Their sentence [of condemnation which God has decreed] from a time long ago is not idle [but is still in force], and their destruction and deepening misery is not asleep [but is on its way].

For if God did not have pity for the angels who did evil, but sent them down into hell, to be kept in chains of eternal night till they were judged;

These are fountains without water, and mists before a driving storm; for whom the eternal night is kept in store.

Instead, continue to grow in the grace and knowledge of our Lord and Savior Jesus, the Messiah. Glory belongs to him both now and on that eternal day! Amen.
