As for you, the anointing which you received from him remains in you, and you don't need for anyone to teach you. But as his anointing teaches you concerning all things, and is true, and is no lie, and even as it taught you, you will remain in him.

 2:19-21 They have gone out from among us but they are not of our number. If they had been of our number, they would have remained with us. But things have happened as they have happened, that it may be clearly demonstrated that all of them are not of us. But you have received anointing from the Holy One and you all possess knowledge. I have not written this letter to you because you do not know the truth, but because you do know it and because no lie comes from the truth.
