I seem to recall many years ago an article talking about the word "plan". You know how sometimes they love to just overanalyze some obscure point to death, like is it sanctification or vindication of Jehovah's name, which one it is I don't even know.
But this article claimed that a plan describes something an man might have, saying plan implies there is some uncertainty about its success. A plan of course can fail for various reasons. Whereas Jehovah with all his super powers, when he PURPOSES something to happen, that means it will happen, just the way he intended. This may have been back in that wonderful book, God's Eternal Purpose, now Triumphing because we say it is.
