These powerful verses in this psalm were written before David was anointed king and in them he shares his trust in the Lord.

1 The Lord is my light and my salvation—
so why should I be afraid?
The Lord is my fortress, protecting me from danger,
so why should I tremble?
2 When evil people come to devour me,
when my enemies and foes attack me,
they will stumble and fall.
3 Though a mighty army surrounds me,
my heart will not be afraid.
Even if I am attacked,
I will remain confident.
4 The one thing I ask of the Lord—
the thing I seek most—
is to live in the house of the Lord all the days of my life,
delighting in the Lord’s perfections
and meditating in his Temple.
5 For he will conceal me there when troubles come;
he will hide me in his sanctuary.
He will place me out of reach on a high rock.
6 Then I will hold my head high
above my enemies who surround me.
At his sanctuary I will offer sacrifices with shouts of joy,
singing and praising the Lord with music.
Psalm 27:1-6 NLT

In verse 4 David writes about living in the "House of the Lord" as he focuses on one thing he seeks. Today think about "whittling down" your life. What is important? Where do you focus? How do you live deeply into your calling?
