Jn 14:10, Jn 8:16, Jn 16:32

Jesus was always with God. Therefore, the words Jesus speaks are the words God speaks in Jesus. In other words, the words of Jesus are the words of God. (Jn 8:29, Jn 16:32, Jn 14:10)

Jn 8:29 And he that sent me is with me: the Father hath not left me alone; for I do always those things that please him.

Jn 16:32 Behold, the hour cometh, yea, is now come, that ye shall be scattered, every man to his own, and shall leave me alone: and yet I am not alone, because the Father is with me.

Jn 14:10 Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works.

Also, the judgment of Jesus is the judgment of God. (Jn 8:16)

Jn 8:16 And yet if I judge, my judgment is true: for I am not alone, but I and the Father that sent me.
