John is not against us learning from preaching and teaching (thankfully!) but warning us against those who are leading people astray through spiritual experiences that at the same time dethrone Jesus Christ. Now he affirms our position and has confidence that we will not be deceived.
“As for you, the anointing you received from him remains in you, and you do not need anyone to teach you. But as his anointing teaches you about all things and as that anointing is real, not counterfeit—just as it has taught you, remain in him.” (1 John 2 v 27)
As for you. Pause. How is it with you and the Holy Spirit? A questions that takes time to answer.
