The Godhead has personal distinctions.

"The Son can do nothing of himself, but what
he seeth the Father do. . . .For the Father
judgeth no man, but hath committed all
judgment unto the Son"
John 5:19,22

One does not act on their own, doing their own

thing. There is a unity in their actions as well as
in their natures; even though they are distinctly
three persons. The Father is not the Holy Spirit,
the Holy Spirit is not the Son and the Son is not
the Father. Three persons, One God, with one
purpose and actions. Three in One. Trinity.

So Jesus claimed to the Jewish leaders that He

does what the Father does, not His own will but
the will of the Father.
