Honor God
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].
—1 John 2:27
Sometimes we give more consideration to what people tell us than to what God has said to us. If we pray diligently, hear from God, but then start asking everybody else what they think, we are honoring people's opinions above the Word of God. This attitude will prevent us from developing a relationship in which we consistently hear from God.
The verse above confirms that we can trust God to instruct us without needing constant reassurance from others. It isn't saying that we don't need anybody to teach us the Word. Otherwise, God wouldn't appoint some to teach in the body of Christ. But it does say that if we are in Christ, we have an anointing that abides on the inside of us to guide and direct our lives. We might occasionally ask somebody for their wisdom, but we need not go constantly to other people to ask them about decisions we need to make for our lives.
