John Gill Commentary John 11:42

"And I knew that thou hearest me always: but because of the multitude that standeth around I said it, that they may believe that thou didst send me." — John 11:42 (ASV)

And I knew that you hear me always
Which was not only a support to the faith of Christ, as man, but is also to his people, whose advocate, intercessor, and mediator he is.

But because of the people which stand by, I said [it] ;
that he was heard, and always heard by God; and, therefore must have great interest in his affection, and knowledge of his will; yea, their wills must be the same:

that they may believe that you have sent me :
for if he had not sent him, he would never have heard him in anything, and much less in everything; wherefore this was a full proof, and clear evidence of his divine mission.
