João 7:14-18 - Bíblia Online

But when it was already the middle of the feast, Jesus went up to the Temple and began to teach. "I have given them thy word; and the world has hated them because they are not of the world, even as I am not of the world. 
The Jews were amazed. They said, "How does this fellow know the sacred writings when he has never learned them?" "I am not asking that thou wilt take them out of the world, but that thou wilt protect them from the Evil One. 
In reply Jesus said to them; "My teaching is not mine, but is his who sent me. "They are not of the world, even as I am not of the world. 
"If any one wills to do Gods will he shall know concerning my teaching, whether it is from God, or I speak my own authority. "Dedicate them in thy truth; thy word is truth. 
"The man who speaks on his own authority is always seeking his own glory. But one who is eager for the glory of Him who sent him, he is true, and therefore is nothing false about him.
