What did Jesus mean when he said, "I and the Father are one" (John 10:30).
Have you read the context?
I will supply it for you to examine.
25 Jesus answered them, I told you, and ye believed not: the works that I do in my Father's name, they bear witness of me.
26 But ye believe not, because ye are not of my sheep, as I said unto you.
27 My sheep hear my voice, and I know them, and they follow me:
28 And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
29 My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
30 I and my Father are one.
31 Then the Jews took up stones again to stone him.
32 Jesus answered them, Many good works have I shewed you from my Father; for which of those works do ye stone me?
33 The Jews answered him, saying, For a good work we stone thee not; but for blasphemy; and because that thou, being a man, makest thyself God.
34 Jesus answered them, Is it not written in your law, I said, Ye are gods?
35 If he called them gods, unto whom the word of God came, and the scripture cannot be broken;
36 Say ye of him, whom the Father hath sanctified, and sent into the world, Thou blasphemest; because I said, I am the Son of God?
What was Jesus doing all his life?
Luke 2:49
And he said unto them, How is it that ye sought me? wist ye not that I must be about my Father's business?
Was he doing his own business?
Or, was he doing his Father's business?
Why didn't he do his own business?
If he was God he would have not had to abandon his own will in order to do the Father's will.
Since his will was different from his Father's will and Jesus chose to honor his Father and mother, he did the Father's will not his own.
God's will is superior to Jesus' will. Jesus Christ was and is subordinate to his Father.
(And so should we be.)
They are different and will always be different
