1 John 4:6 Spirit of Truth or Error

1 John 4:6 says, “We are of God. He who knows God hears us; he who is not of God does not hear us. By this we know the spirit of truth and the spirit of error.” John is saying that we who teach the things of God are heard by those who know God. What qualifies any teacher is not apostolic succession or ordination by men, but the spirit of truth rather than error. When people give in to the spirit of falsehood, contradicting the teachings of the Apostles, claiming the Bible is just the teachings of men, they become false prophets, falsely claiming to be speaking for God.
