You may say to yourself, “How can we recognize a word that the Lord has not spoken?” If a prophet speaks in the name of the Lord but the thing does not take place or prove true, it is a word that the Lord has not spoken. The prophet has spoken it presumptuously; do not be frightened by it.
And if I have prophetic powers, and understand all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but do not have love, I am nothing.
