Jesus' Crucifixion was the fulfillment of centuries of trust that had been placed in God. His sacrifice took the place of all other sacrifices in redemption for our sins. Through it, we are guaranteed eternal life. The COVID vaccines stave off death for a while; Jesus' death and resurrection defeat death entirely.
Thus, today I feel especially protected. While the vaccine gives me some amount of comfort, I feel better for the assurance that Jesus has given us. Because of Him, death holds no power over us anymore.
