Through their faith and their loving union with God in the person of Christ, Christians become fundamentally spiritually equipped to overcome the fear of death. They’re saved from spiritual death and are no longer afraid of biological demise. It’s precisely their faith in the Resurrection of the Lord which fills their souls with courage, hope, optimism and patience. The whole of the otherwise insurmountable problem of death undergoes a change of content and is transformed into an encounter and direct communion with the person of Christ. By the same token, time, from being a drift towards death, a movement towards meaningless darkness, becomes a movement towards resurrection, towards an effulgent revelation.
