Let what you heard from the beginning remain in you. If what you heard from the beginning remains in you, then you will remain in the Son and in the Father.
But as for you, the anointing you received from him remains in you, and therefore you do not need anyone to teach you. This same anointing teaches you everything and is true and not false, so abide in him just as he taught you.
Finally, brethren, let your minds be filled with whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is pleasing, whatever is commendable, whatever is excellent, whatever is worthy of praise.
