I will get to that. Yes, it can be explained bit before I even go into that, we have to go over a few things. Such as two persons who are married are spoken of as one. Remember also that Jesus spoke to the Father, and there was the time that the Father spoke from heaven, calling Jesus his Son. Matthew 3:17 - "And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased." Now clearly Jesus was not speaking to himself. Also Jesus prayed to his father in heaven, not a spirit within himself.
