The shepherds would believe the angel’s report that they would look upon the Savior of the world, Christ the Lord. But they weren’t convinced until they met the baby themselves.
It took an actual meeting of the Christ child before they could commit themselves to what they had heard beforehand. Once the meeting took place they were all in. They left the stable glorifying and praising God.
A person can hear about Jesus all their life but they won’t be able to fully experience the joy he offers until they meet Him for their self. Pray that people will desire to have a personal relationship with Jesus and not be content with another’s testimony.
