You might say to yourself, “How can we know that the Lord did not speak the message?” If what the prophet proclaims in the name of the Lord is not true and it does not happen, then the message was not proclaimed by the Lord. The prophet has spoken presumptuously, you should not fear him.
My son, concentrate attentively on my words; pay heed to the instructions I pass on to you. Do not let them slip from your mind; keep them forever in your heart.
