'Ages' in the Bible

But mercy was shown me in order that in me as the foremost of sinners Christ Jesus might display the fulness of His long-suffering patience as an example to encourage those who would afterwards be resting their faith on Him with a view to the Life of the Ages.

and to the King of the ages, the incorruptible, invisible, only wise God, is honour and glory -- to the ages of the ages! Amen.

Exert all your strength in the honourable struggle for the faith; lay hold of the Life of the Ages, to which you were called, when you made your noble profession of faith before many witnesses.
