Jesus of Nazareth certainly was a product of his time.  It is His Divine nature that is for all time, and if you examine writings in Christology, theological essays on scriptural accounts, and Biblical studies from recent times (our knowledge and understandings of Scripture continue to unfold even to this day, all of it accumulative), Jesus came to know of it in gradual phases, even to His death.  In the Garden of Eden He says "Lord, let this cup pass from me..." and while on he cross, "Father, Father, why have you abandoned me?"  Not the words of one who is filled with certainty of their Messianic mission, now is it?  Jesus was born in occupied Palestine, was an observant Jew, lived 30 some years before starting his public mission, and died on a cross as a seditionist in the Roman Empire.  I think you may have taken a wrong turn in your studies about the dual nature of Jesus.
