Sorry, Charlie. Not even close.
Isa 22:20 In that day I will call my servant Eli'akim the son of Hilki'ah,
Isa 22:21 and I will clothe him with your robe, and will bind your girdle on him, and will commit your authority to his hand; and he shall be a father to the inhabitants of Jerusalem and to the house of Judah.
Isa 22:22 And I will place on his shoulder the key of the house of David; he shall open, and none shall shut; and he shall shut, and none shall open.
Isa 22:23 And I will fasten him like a peg in a sure place, and he will become a throne of honor to his father's house.
So if the key is being placed upon the shoulder of Christ, as you are stating...
then you are equating Christ with the servant, rather than the king (Hezekiah). To me, that sounds dangerously close to denying the divinity of Christ...
If that's what you choose to believe, well, this is a free country, but you may wish to consider the implications.
I don't have a problem with it...Jesus is not YET the King...But He will be...
