Just like he did not come to do his own will, his teaching is not his own. Yeshua clearly distinguishes himself from the G-d, saying, ‘My teaching is not mine, but His Who sent me. If anyone’s will is to do His will, he will know whether the teaching is from the G-d or whether I am speaking on my own authority.’ (Yokhannan / John 7:16-17).
Again, Who is the G-d from Whom Yeshua received his teaching?
As Yeshua says, ‘…I have not spoken on my own authority, but the Father Who sent me has Himself given me a commandment—what to say and what to speak. And I know that His commandment is the Life of the World to Come. What I say, therefore, I say as the Father has told me’ (Yokhannan 12:49-50).
As Yeshayahu HaNavi (the prophet Isaiah) says,
‘All your children will be taught by HaShem, and great will be the peace of your children.’
— Yeshayahu (Isaiah) 54:13
And as the Lord Yeshua says,
‘It is written in the Prophets, ‘And they will all be taught by G-d.’ Everyone who has heard and learned from the Father comes to me…’
— Yokhannan 6:45
As always, in context, HaShem is the G-d and Father of the Lord Yeshua.
