3 Nephi 1:15 – 16
“And it came to pass that the words which came unto Nephi were fulfilled, according as they had been spoken; for behold, at the going down of the sun there was no darkness; and the people began to be astonished because there was no darkness when the night came.
And there were many, who had not believed the words of the prophets, who fell to the earth and became as if they were dead, for they knew that the great plan of destruction which they had laid for those who believed in the words of the prophets had been frustrated; for the sign which had been given was already at hand.”
The first Christmas Eve. I’m trying to imagine that. “Astonished” might be an understatement when the sign was given. They could see the sun go down but the sky remained light!
God does fulfill His promises. He tells His prophets what to reveal. He answers our sincere prayers.
What a fitting sign (no darkness) to give for the coming of Jesus Christ! He is, literally, the Light of the world!
