When Jesus came to earth and was born in a barn in Bethlehem, the shepherds, wise men, and all the others that got to physically see Him on earth were privileged. When He died on the cross and rose again, some of the disciples got to see Him right away while others, Thomas in particular, would not believe until they saw Him. Even though Jesus revealed Himself to Thomas, wiping away his doubts, Jesus said that those who believe without seeing Him will be blessed. That means us because we believe in Jesus without being able to see Him except through people who have allowed Christ to come in and transform their lives. While we are here on earth, we can be the Nativity Scenes that people need to see in order to believe.
