John 14:11

11 Believe me when I say that I am in the Father and the Father is in me. If not, believe because of the things I do.

John 14:11 Meaning and Commentary

John 14:11

Believe me that I am in the Father, and the Father in me,
&c.] Take my word for the truth of this; you may assure yourselves that nothing is more certain; but if you will not believe upon my saying so, either believe for the sake of the doctrines I have preached unto you, which are such as never any mere man spoke, and which have been delivered in such a manner, and with such authority, as never were by man. Some copies read, by way of interrogation, and so the Ethiopic version; and the Vulgate Latin version reads, "believe ye not?"

or else believe me for the very work's sake:
meaning his miraculous works, such as raising the dead, cleansing the lepers, causing the deaf to hear, and giving sight to the blind; and which were such as none but a divine person could ever perform.

John 14:11 In-Context

9 Jesus answered, "For a long time I have been with you all; yet you do not know me, Philip? Whoever has seen me has seen the Father. Why, then, do you say, "Show us the Father'?
10 Do you not believe, Philip, that I am in the Father and the Father is in me? The words that I have spoken to you," Jesus said to his disciples, "do not come from me. The Father, who remains in me, does his own work.
11 Believe me when I say that I am in the Father and the Father is in me. If not, believe because of the things I do.
12 I am telling you the truth: those who believe in me will do what I do - yes, they will do even greater things, because I am going to the Father.
13 And I will do whatever you ask for in my name, so that the Father's glory will be shown through the Son.
