John 14:16,17

I will pray the Father, and He will give you another Helper, that He may abide with you forever-the Spirit of truth, whom the world cannot receive, because it neither sees Him nor knows Him; but you know Him, for He dwells with you and will be in you.

The Holy Spirit is within us to help us succeed in this world.  He knows the things of God and will bring us a revelation of the word and knowledge.  When we keep ourselves open and listen for His guidance, our lives will be transformed.  God has given us the greatest resource for transformation, and He lives within us.
