John 10:19

Then the Jews began to argue with one another, saying, “How can this man give us His flesh to eat?”

So a division occurred in the crowd because of Him.

So then some of the Pharisees were saying, “This man is not from God, because He does not keep the Sabbath.” But others were saying, “How can a sinful man do such signs?” And there was a division among them.

We are from God. The one who knows God hears us; the one who is not from God does not hear us. From this we know the spirit of truth and the spirit of error.
