David singing to the Lord. 
The Psalms are probably the richest source of theology in the Bible. Take Psalm 3:

O Lord, how my adversaries have increased!
Many are rising up against me.
Many are saying of my soul,
“There is no deliverance for him in God.” 

But You, O Lord, are a shield about me,
My glory, and the One who lifts my head.
I was crying to the Lord with my voice,
And He answered me from His holy mountain. 
I lay down and slept;
I awoke, for the Lord sustains me.
I will not be afraid of ten thousands of people
Who have set themselves against me round about.

Arise, O Lord; save me, O my God!
For You have smitten all my enemies on the cheek;
You have shattered the teeth of the wicked.
Salvation belongs to the Lord;
Your blessing be upon Your people! 

Here are ten statements from the Psalm about God and how he cares for you in your circumstances:

  1. God is your shield when you are scared and need protection
  2. God is your glory when you are scorned
  3. God is the One who lifts your head when you are downhearted and need encouragement
  4. God hears your prayers when you cry out and need to be heard
  5. God supplies when you are in need and need sustaining
  6. God smites your enemies when you are under attack and need to be defended
  7. God saves you when you are in trouble and need to be rescued
  8. God shatters the teeth of the wicked when you are the subject of slander and need an advocate
  9. God is the only hope of salvation when you are out of options and need a way through
  10. God blesses his people when they obey him and need approval
