Lux venit

 Built into us by the Creator is a longing to understand God and eternity, to believe there is really hope for humanity:

"By sword, by flame
In death solemn ages passed,
And voices young grow old & weary
Holding fast - hope for the dawning"

The Christian good news is that God sought out humanity by sending Jesus Christ, who brings light to us:

"Lux venit, Sursum corda." Arise, shine! For your light has come!

Those lyrics are from the song below. It's years old, but "Lux Venit" from this album by Michael W. Smith moves me every time I hear it. Enjoy.
