Psalm 27

The LORD is my light and my salvation-
whom shall I fear?
The LORD is the stronghold of my life-
of whom shall I be afraid?
One thing I ask of the LORD ,
this is what I seek:
that I may dwell in the house of the LORD
all the days of my life,
to gaze upon the beauty of the LORD
and to seek him in his temple.
For in the day of trouble
he will keep me safe in his dwelling;
he will hide me in the shelter of his tabernacle
and set me high upon a rock.

Jesus said:

"I am the light of the world. He that follows me shall not walk in darkness, but shall have the light of life."

John 8:12
