Objection, your honor. You don't have a subject and a predicate. You have subject and a dangling linking verb/contraction. It only qualifies as a predicate if the linking verb connects to a noun or an adjective that MODIFIES or describes the Subject in some fashion. IOW, " I am hungry" (predicate adjective) Or "I am male". (predicate nominative) So while "I am" is an expression of Biblical importance, and spiritual significance....grammatically its actually a clause representing an incomplete thought. In fact, in the Bible, it was used as a subordinate clause [i]Jesus said unto them, Verily, verily, I say unto you, Before Abraham was,[b] I am[/b].[/i] -----John 8:58

I raise you one: "Go."
