“The Atonement was clearly efficacious for mortal men who lived after the Savior’s ordeal in the Garden and on the cross. But what of mortals who lived before the Savior or even further back in time to spirits of the premortal realm? Does the Atonement reach that far? Is it infinite in time both retroactively and prospectively … ? The laws of justice could recognize the benefits of the Atonement before the purchase price was ever paid, because his promise, his pledge, his credit was ‘good for it,’ and everyone who honored their first estate knew it” (Callister, Infinite Atonement, 72–74).
