The expression of a thought always tells what the holder of it is.
God, Satan, and man, may express each one his thoughts upon a given subject. Each of them would, as certainly as the thought was expressed, reveal himself in the thought so expressed, and not only the measure (correct or incorrect) of that about which the expression is.
We see God's, Satan's, and men's thoughts about Job, in the book of that name; and Job's own, too, about himself.
God's alone were according to truth, and infallible; and all the rest were wrong, or only partially right. But God's thoughts revealed the character of the speaker, as much as did Satan's his character, and of men, each his own.
Moses gave his thoughts about Israel, once and again. So did God give his, and Satan his, and Israel its own. Each speaker, at least showed out himself;-though only one told the truth perfectly, according to divine light.
What a different thing a saint is as thought of by Christ; by Satan, by the world, by himself.
And what a contrast between John 17 and Rev. 12 in this connection. Christ talking to His Father about His disciples, and Satan accusing the brethren!
