Granville Sharp's rule states that when you have two nouns, which are not proper names (such as Cephas, or Paul, or Timothy), which are describing a person, and the two nouns are connected by the word "and," and the first noun has the article ("the") while the second does not, *both nouns are referring to the same person*. In our texts, this is demonstrated by the words "God" and "Savior" at Titus 2:13 and 2 Peter 1:1. "God" has the article, it is followed by the word for "and," and the word "Savior" does not have the article. Hence, both nouns are being applied to the same person, Jesus Christ.
Again in Proverbs who is God and king describing? No one. They have to be describing someone for the rule to apply.
