We needed Thomas to doubt.
Some say that Jesus was just a good man and a prophet- if that is true then we have no hope or reason to hope, because Jesus as just a man couldn’t pay for our sins and His death would be meaningless.
These same people say Jesus coming back from the dead and appearing to the deciples was just a vision given to the deciples by God of the man coming and talking with them, but that Jesus Himself was not actually, Physically there.
But when Jesus was with the deciples He met a friend who was so broken by His death that he couldn’t believe that the Jesus he saw was more than a vision or a trick of his mind. Jesus had to encourage Thomas to touch Him. To touch His scarred hands and the wound in His side and to know through that physical touch that this was no illusion, vision, or trick of the mind, He was actaully there; smiling, laughing and chatting with His friends. If Thomas hadn’t doubted his own eyes and needed the physical connection to Jesus, then those people who claim He was just a vision or illusion of grief wouldn’t have an eye witness account that could hold water, but Thomas actually touched Him, you can’t touch a vision, and if he hadn’t doubted that Jesus coming back was true -like so many still doubt today- then maybe we wouldn’t have the record of that human to human, flesh to flesh, touch that shows once and for all that it was a physical and real risen savior standing there. Thank you Thomas for your doubt, because it was needed for those who need proof beyond Faith.
