”A man does not cease to be himself when God uses him.  His powers are not changed, they are merely controlled so as to effect the very purpose, and no other, which God would accomplish.  It is as if a musician were to play first upon a flute and then upon a cornet; each instrument would give its own sound wholly different from the other, but the breath that makes the sound and the genius that inspires the music is the same.  Moses, David, Isaiah, James, Paul, and Peter were so many different instruments, though not mechanical instruments, each with personal peculiarities of his own, but all were used by the same God as the media of communicating with men.”  (H. H. Tucker)
