The Importance of Knowing the Holy Spirit

In John 16 verse 7, Jesus says the world can't receive the Spirit because it doesn't see Him or know him. But then He added, you know Him, for He dwells with you and will be in you. It means that the Holy Spirit who was in the life of Jesus from the moment of His conception right through the whole of His ministry until the end of His life went by the power of the eternal Spirit He offered himself as a sacrifice to the Father.
