Psalm 42: 1 - 11 (CSB)
Psalm 42 reminds us that we were created to have a deep need for God. 
There is no deeper hole than the human soul, and God is the only one with the capacity to fill it. He alone can satisfy. 
When our souls are parched and thirsty for God, we need to be honest with ourselves, run to God, and speak to our souls to put our hope in Him.
