The opening chapter of the book of Proverbs establishes the foundation of knowledge:
“The fear of the Lord is the beginning of knowledge; fools despise wisdom and instruction.” (Proverbs 1:7).
James Montgomery Boice has this note about knowledge in his commentary on Genesis 40 (p 952):
“He who knows not and knows not that he knows not is a fool; shun him.
He who knows not and knows that he knows not is a child; teach him.
He who knows and knows not that he knows is asleep; awake him.
He who knows and knows that he knows is a wise man; follow him.”
Boice places Joseph into the last category. He knew and he knew that he knew. As a result he was not only wise but powerful, yes, powerful even though he was in prison.
I’m reminded also of the apostle’s words to the Galatians which is set in the context of his argument about slavery and freedom:
“But now that you have come to know God, or rather to be known by God…” (Galatians 4:9).
Browse the debate between Jesus and his opponents in John 8:12-59 and the theme of knowledge and freedom is likewise developed. True knowledge brings liberation – that freedom in found in knowing Jesus.
