Immediately upon recognizing Jesus, Thomas responded, "My Lord and my God" (John 20:24-28). This is the first time any of the disciples dared to call Jesus! God. It was an amazing declaration that Satan wants us to miss, so he suggests we focus on Thomas' doubts and not on his revelation.
Jesus said, "blessed are those who have not seen but believe" (John 20:29). Is this a pronouncement that we who believe without seeing Jesus' physical body are better than Thomas? Do we have a right to feel spiritually superior to Thomas?
If we do, we have forgotten Ephesians 2:10. "By grace you have been saved through faith, and that not of yourself, it is the gift of God, lest anyone should boast". Jesus' words mean exactly what he said. We are blessed who believe and have not seen because God has blessed us with the gift of belief. Without that, we would be lost forever.
