1 John 2:20 " But you have an unction from the Holy One, and you know all things."
Have you ever been around a know-it-all? Are you a know-it-all? In a negative sense, it's someone who thinks they know everything, they know more than other people, or they don't need anyone's advice, they simply think they "know it all".
According to 1 John 2:20, if you are born again and filled with the Holy Spirit, did you know that you have a huge advantage? The apostle John says something very, very powerful in this verse. You have the One that knows all things right there on the inside of you, in your born again Spirit-filled spirit! That's awesome!
He says that you have an unction, that's a word that means something smeared on as a scented ointment. In the context of this verse, the unction refers to the Holy Spirit Himself! Everything that you need to know is in your spirit. 1 Corinthians 2:10 says, " But God reveals them unto us by His Spirit", and 1 Corinthians 2:12 says, "We have received the Spirit which is of God; that we might know the things freely given to us of God".
Verse 13 tells us exactly how to draw out this "knowing" - "which things also we speak, not in words which man's wisdom teaches, but which the Holy Ghost teaches". Praying in the Spirit, or praying in tongues is powerful. When we pray in tongues, we hear the mind of Christ for any specific issue or problem we are facing. 1 Corinthians 14:13 says, "wherefore let him that speaks in an unknown tongue pray that he may interpret". That's where you "know it all", through Him.
So whatever question you have today, you have an unction, and you know all things by the Spirit of God living on the inside of you. Ask God for the interpretation, and you'll get the answers that you need, and God's plan for your life. See, even know-it-all's can never know it all without God, but aren't you glad YOU know the One who knows it ALL!
