Jesus identified the Father as a Spirit in
John 4:23-24. When you think of the Father, you should think of the eternal, omnipotent, omnipresent Spirit.
The angel identified the Son as "that holy thing which was born of Mary" (
Luke 1:35). Thus, the Son was the humanity which was born of Mary.
The Father is not the Son, nor is the Son the Father. However, Jesus is both Father and Son.
Your spirit is not your flesh, nor is your flesh your spirit. However, you are not two persons.
I hope this helps.
