There is a definition that is taken as, summarily, "God gets what God wants," and so he must not want "all to be saved" since not all are saved... however, I see it more accurately as, and this is probably not word for word either, "God wants everyone to come to the knowledge of salvation," that is 'to know salvation, that is Christ." Is not the desire for each 'comer's' involvement by his/her coming (which is an action word) also contained within that will?
Jesus said, "I will draw all men to Me" and also, "no man can come to Me unless the Father draws him" so tell me Who, then, exerts the initial draw? Does anyone know? Yet, that not everyone comes to know salvation equates to...God not wanting them to come rather than them not willing to come?! Is it out of God's character to offer regard the will of man, I mean isn't considering an individual's will a might too humble to be God? Yet, Jesus said, "Come, and learn of me... I am humble and lowly of heart..."
Oh well, anyway. I came here 10 years ago with the hopes of finding the Christian rendition of the Borg, all that we could accomplish if we were all actually one. Just think of the potential to dissolve the world in a total blazing glory... I must be delusional.
