Though you grind a fool in a mortar,
grinding him like grain with a pestle,
you will not remove his folly from him.
It is a sad situation to be in if you are a fool.
Those who are in Christ, when they are "ground" by the situations of life, will be sanctified by the process. They will go to God and His word, and the truth will sanctify them.
But not the fool.
Pray today that you are not this fool. Ask God to peel the scales from your eyes and let you see.
