Do you think that God was not aware of the wedding at Cana? Do you think He actually was persuaded to change some "divine plan" for revealing the divinity of Jesus, just because Mary asked Him to perform miracle at a wedding? If so, you once again fail to reckon with the true nature of God.
And you fail to attend to the details of the text for the sake of your doctrine.
How would the writer of the book of Hebrews measure up to your exegetical standards with his expository comments about Melchizadek?
Good night.
