You can't have the Father without the Son, because in a true sense both are one. We must try the spirits to see if they are from God. You test them by what you know the Bible plainly teaches. As for you, the anointing you received from him remains in you, and you do not need anyone to teach you. The third mark of an antichrist is they will seek to deceive the faithful.
Deception is the hallmark of a false teacher.
Biblical terms for false are wolves in sheep's clothing and angels of light. These terms define a deceitful spirit. Satan's work is a counterfeit. The counterfeit is designed to look like the real thing. They can make another gospel sound like the real thing.
