Final answer:
Thomas is the disciple who doubted Jesus' resurrection until he saw Jesus and His wounds, leading to Thomas's declaration of belief.
Step-by-step explanation:
The disciple who would not believe Jesus was resurrected until he saw Him with his own eyes was C. Thomas. This event is known as The Incredulity of Thomas and is recorded in the Gospel of John 20:24-29. When Jesus appears to Thomas, He invites him to touch his wounds, leading Thomas to profess his faith by exclaiming, "My Lord and my God!". This expression of doubt followed by an affirmation of belief emphasizes the significance of faith and personal witness within the Christian tradition. This story is also a poignant reminder of Jesus' message and the enduring legacy of the original disciples or apostles who traveled to spread His teachings.
