¹⁷ Anyone who chooses to do what God wants will know about my teaching. They will know whether it comes from God, or whether it comes from my own thoughts. ¹⁸ A person who teaches his own ideas wants people to think that he himself is great. But I want to show that the one who sent me is great. A person like that is honest and there is nothing false in him. ¹⁹ Moses gave God's Law to you. But not one of you obeys that Law. Why are you trying to kill me?’
