I was stressed out at work today and, towards the end of the day, felt inspired to open up my Bible.  This is what I read.
Psalm 121

1 I lift up my eyes to the hills—
where does my help come from?2 My help comes from the LORD,
the Maker of heaven and earth.

3 He will not let your foot slip—
he who watches over you will not slumber;

4 indeed, he who watches over Israel
will neither slumber nor sleep.

5 The LORD watches over you—
the LORD is your shade at your right hand;

6 the sun will not harm you by day,
nor the moon by night.

7 The LORD will keep you from all harm—
he will watch over your life;

8 the LORD will watch over your coming and going
both now and forevermore.
