What he is trying to say is, in Islam the God and the Jesus are two separate entities. Jesus was only human but gifted and blessed by God and was His prophet.

Although in English we refer God as "He", in Islam God and angels does not have a gender.

Also God is not Jesus' father, Jesus was a blessing to the virgin Miriam(Maria). Miriam gave birth to Jesus without any father. This is counted as one of the many miracles of Jesus.
