16) And I will pray tthe Father, and He will give you another helper, that He may abide with you forever; 17) the Spirit of truth, whom the world cannot receive, because it never sees Him, for He dwells within you and will be in you. (John 14:16-17)
The Greek word for counselor is parakletos, which also means "advocate" and "comforter". Literally, parakletos means "one called alongside". The Holy Spirit's purpose, then as well as now, was to come alongside mankind and help us know and do the Father's will. He convicts us when we do something wrong, guides us along the right path, nudges us to get started doing God's will, and directs our course, but He controls only as much of us as we surrender to Him.
Keep this in mind, that whatever God wanted, the Holy Spirit revealed to the man and the man manifested it on Earth. God wanted His Kingdom rulership to come to Earth, but He could only do this through His children who are connected to Him by the Spirit of God.
10) But God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God. 11) For what man knows the things of a man except the spirit of the man which is in him? Even so no man knows the things of God except the Spirit of God. 12) Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given to us by God. 13) These things we also speak, not in words which man's wisdom teaches but which the Holy Spirit teaches, comparing spiritual things with spiritual. (I Corinthians 2:10-13)
With God's Spirit living inside of man and directing his thoughts and life according to God's will, man could manifest God's Kingdom on the Earth.
