How is the “I” in “the Father is greater than I” understood as referring to Jesus’ human nature while the other I in John 8:58 to his divine nature?

In Gospel of John 14:28, Jesus says, “the Father is greater than I,” which is often used in arguments about the relationship between the Father and the Son. Some interpret the “I” here as referring specifically to Jesus’ human nature (e.g., in an incarnational or functional sense), rather than His divine nature. However, in the same Gospel, Jesus also says in John 8:58, “before Abraham was, I am,” where the “I” appears to refer to His divine identity. My question is: - On what basis do interpreters distinguish the “I” in John 14:28 as referring to Jesus’ human nature, while the “I” in John 8:58 refers to His divine nature? - How do major Christian traditions (e.g., Trinitarian theology) justify this distinction within the same speaker and Gospel context?
