1 John 2:27 is GREAT news for born again believers in Jesus Christ!
27 But as for you, the anointing (the sacred appointment, the unction) which you received from Him abides [permanently] in you; [so] then you have no need that anyone should instruct you. But just as His anointing teaches you concerning everything and is true and is no falsehood, so you must abide in (live in, never depart from) Him [being rooted in Him, knit to Him], just as [His anointing] has taught you [to do].
What exactly is this "unction" that we have received? John 16:13 tells us clearly:
13 Howbeit when He, the Spirit of truth, is come, He will guide you into all truth: for He shall not speak of Himself; but whatsoever He shall hear, that shall He speak: and He will shew you things to come. KJV
The "Spirit of Truth", the "Holy Spirit" is the Unction! He IS the Anointing! HE is the One Who will teach us the TRUTH of God's Word! 1 John 2:27 isn't saying that we don't need to receive from the ministry of a teacher. It is simply saying that no human can teach us individually what the Word of God means to us personally! Only the Spirit of God can do that! I would encourage you to pray Psalm 25:5 the next time you sit down to study the Word of God!
5 Guide me in Your truth and faithfulness and teach me, for You are the God of my salvation; for You [You only and altogether] do I wait [expectantly] all the day long. AMP
This allows the UNCTION, the Spirit of God, to make the Word real to us! AMEN! Here is Hillsong Live with "Love Like Fire":
