Does John 12:41 prove that Jesus is Yahweh?

Greg Stafford,in an essay he wrote on this topic in response to James White,summarizes:

"The teaching of John 12:41 is simple,straightforward and otherwise(that is,apart from trinitarianism)clear,Isaiah saw the "glory" of the Christ's humanity,suffering,and death for our sins while being dishonored among men,as a man,which teaching John develops throughout John 12 and specifically from verse 16 onward.(see John 12:16,23,32-34,37-41),using the same verbs(doxazo,hypso'o,pistueo,and horao)and the same substantive(doxa)that we find in the LXX of Isaiah 52:10,13,14,15 and Isaiah 53:1,2,and 4.John observes that,like the suffering servant of Isaiah 52& 53(specifically 53:1 which he quotes in John 12:38),the crowd did not "put faith in him (Jesus)"(John 12:36,37 [where,again,in both texts and in verse 38 we find forms of the verb for "believe," pistueo]),which is the same language Isaiah used when speaking of Messiah:"Jehovah,who has believed(LXX: epistuese(form of pistueo)our report?And to whom has the arm of Jehovah been revealed?"Is. 53:1,John 12:38
