This Psalm explains what I have come to understand: my thoughts are futile. Faith is what matters. Faith does not require thinking.

Psalm 94:8-11
Understand, you senseless among the people;
And you fools, when will you be wise?
He who planted the ear, shall He not hear?
He who formed the eye, shall He not see?

He who instructs the nations, shall He not correct,
He who teaches man knowledge?
The Lord knows the thoughts of man,
That they are futile.
