Jesus knew what to say. He always knew the right thing to say because he based his advice on Jehovah’s wisdom, never his own.
They have such little respect and honour for Jesus. They are claiming he doesn’t have wisdom of his own to exercise and is not able to know what to say in his own right.
we must make sure that the counsel we give is based, not on our own thoughts, but on God’s Word.
Since Jesus lacks any ability to act on what he feels and knows to be good, how much more so is this the case for JWs. Their own thoughts are always bad and must never coincide with God’s thoughts. The Watchtower is just training them to accept its own thoughts, regardless of whether it makes sense to a jw or not.
