Because HE was given authority from God just as all the works He did was from God,
Joh_5:36 But I have greater witness than that of John: for the works which the Father hath given me to finish, the same works that I do, bear witness of me, that the Father hath sent me.
But you see,
Joh_8:54 Jesus answered, If I honour myself, my honour is nothing: it is my Father that honoureth me; of whom ye say, that he is your God:
Joh_20:17 Jesus saith unto her, Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and to my God, and your God.
How does God Honour God.
As my dad said after telling me Jesus is God, " I have seeing God and I have Seeing Jesus",
funny thing is so have I. But you dont believe that.
As I said before, people who are called dont go around boasting about it.
