When Jesus was born, the angel told the shepherds that they should not be afraid.
The angel did not say they should not be afraid... as long as they trusted in God before they died.
The angel brought good news of great joy for all people.
The angel did not say the good news was for a select few and to hell with the rest of those pagan , heathen, non-believing haters of God... like we all used to be.
The angel announced the birth of a savior.
Not a savior of less than 20% of all humanity but a savior that was "the lamb of God" that took away the sins of the whole world. If only a select few were ultimately saved, the angel was really bringing bad news for the majority of mankind.
Hallelujah what a savior!
