It's interesting to see how God used light to reveal Jesus when He was born--by a star.
The wise men who came from somewhere in the east had an understanding that this unusual Star meant that the King of the Jews had been born (Matthew 2:1-11). In obedience to that revelation (prepared hearts!), they kept at their quest to find this baby King until that same star actually led them to the very spot. I love how God uses the symbolism of darkness and light here--stars don't shine during the day. It was in the darkness that the wise men found Jesus.
Centuries before, a prophet named Balaam had actually called the coming Messiah a Star:
"I see Him, but not now;
I behold Him, but not near;
A Star shall come out of Jacob;
A Scepter shall rise out Israel...
Out of Jacob One shall have dominion."
(Numbers 24:17, 19)
And the apostle Peter, writing years after Jesus' resurrection, uses the same symbolism to call us to the Light of Christ:
"And so we have the prophetic word confirmed,
which you do well to heed
as a light that shines in a dark place,
until the day dawns and the
morning star rises in your hearts..."
(II Peter 1:19)
