I think we're involved in a time continuum "do-over" (un-merited favor) scenario with the victorious sons of light defining or more appropriately "unraveling" the theme of redemption which facilitates what God (who exists outside of our time continuum*) has called pre-destination. "everyone who is found written in the book will be saved"
*an object in motion actually experiences time at a slower rate than one at rest.
