John Gill

And he said unto me, son of man, can these bones live?.... Is there any probability of it? is there any reason to believe they shall live? can any ways and means be devised, or any methods taken, to cause them to live? and I answered, O Lord God, thou knowest; the prophet does not pronounce at once that it was improbable and impossible; he knew indeed it was not probable, or possible, that these bones should revive of themselves; and he knew that neither he nor any creature could quicken them; but he wisely refers it to an omniscient and omnipotent God, who knew what he could and what he would do: the conversion of sinners is not of themselves, nor of ministers, but of God; it is wholly owing to his will and power, Joh 1:13 nothing else can make it probable, or possible.
