The Consequences of Unbelief

Luke 1:18-22

18  And Zacharias said unto the angel, Whereby shall I know this? for I am an old man, and my wife well stricken in years.
19  And the angel answering said unto him, I am Gabriel, that stand in the presence of God; and am sent to speak unto you, and to show you these glad tidings.
20  And, behold, you shall be dumb, and not able to speak, until the day that these things shall be performed, because you believe not my words, which shall be fulfilled in their season.
21  And the people waited for Zacharias, and marvelled that he tarried so long in the temple.
22  And when he came out, he could not speak unto them: and they perceived that he had seen a vision in the temple: for he beckoned unto them, and remained speechless.
