NKJV 365 Day Reading PlanЗагвар

Finished is better translated as “accomplished” or “fulfilled”— not meaning Christ’s life is ended, but showing His divine plan of salvation has now been completed. Bowing His head, He gave up His spirit: St. John Chrysostom writes that Christ did not die first, with His head falling as a result of death. Instead, as Lord even of His own death, Jesus first bowed His head, and then willingly gave up His spirit.
