He is the True Light coming into the world

"Oh, send out Your light and Your truth!
Let them lead me;
Let them bring me to Your holy hill
And to Your tabernacle.
Then I will go to the altar of God,
To God my exceeding joy;
And on the harp I will praise You,
O God, my God." - Psalm 43:3-4

 He has sent forth His Light and His Truth into our world, in human likeness, as a baby born in poverty, and He does lead us by that True Light into the place where He dwells. From this all our joy comes: that God became man and dwelt among us, bringing light into our darkness and truth into the sea of lies surrounding us, that we might know Him and draw near to Him.
