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.
Finally, brethren, let your minds be filled with whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is pleasing, whatever is commendable, whatever is excellent, whatever is worthy of praise.
