I answered one of yours so now it is your turn to answer (no, you don't get to play the role of Inquisitor here).
Was Jesus lying when He said: "And He who sent Me is with Me"? Yes or No?
No.
And he that sent me is with me: the Father hath not left me alone; for I do always those things that please him. (John 8:29 KJV)
The Father was with Jesus. The Father has not left him alone. Jesus always did the things that pleased the Father.
So are the Father and the Son the same person?
Yes or no?
