Final answer:
Jesus presented himself to his disciples and proved he was alive on the third day after his crucifixion, an event that is described in the New Testament and is central to the Easter celebration.
Step-by-step explanation:
According to the events described in the New Testament of the Bible, Jesus presented himself to his followers and gave many convincing proofs that he was alive on the third day after his crucifixion. This event is part of the Christian belief in the resurrection of Jesus, which is celebrated every year as Pascha (Easter). Followers witnessed the empty tomb and were soon after comforted by Jesus himself, with accounts of these interactions chronicled in the Gospels of Matthew, Mark, Luke, and John. Noteworthy is the Incredulity of Thomas, where one of the apostles, Thomas, needed to see and touch Jesus' wounds to believe that he had truly risen, which happened a week after the resurrection.
