Many will say that Joseph prospered because God ordered his steps, and God did. Many will say Joseph prospered because God blessed him, and God did.
But Joseph could have lain with Potiphar's wife, could have been sullen and morose and not interpreted the dreams, could have been dejected and asked Pharaoh what he, a prisoner, could do to help Pharaoh.
He did not. He stayed faithful to God! That is why he was blessed. Not because he was Jacob's son, not because he was Joseph.
He was faithful.
