Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world. 1 John 4:1
"1 John refutes the defectors with sound doctrine, exhibiting no tolerance for those who pervert divine truth.
He labels those departing from the truth
---as “false prophets” (4:1),
---“those who are trying to deceive” (2:26; 3:7),
---and “antichrists” (2:18).
He pointedly identifies the ultimate source of all such defection from sound doctrine as demonic (4:1-7)."
