The Holy Spirit knows all things, and He's also everything to us. He's all you could ever want.
For example, did you know that the Holy Spirit is a healer? That's the Spirit that was referred to in Romans 8:11: " But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you." If He lives in you, it makes no difference what sickness or disease you've been diagnosed with; there'll be a change. He'll effect a cure in you.
If you're a student, He's the one you need to make you excellent and give you success in your academics. He knows all things and will teach you everything you need to know about life. Jesus said of Him, " He shall glorify me: for he shall receive of mine, and shall shew it unto you" (John 16:14).
The Holy Spirit will take that which belongs to Jesus —His wisdom and knowledge— and unveil them to you. Jesus is the embodiment of all wisdom and knowledge (Colossians 2:3), but the Holy Spirit will take from all that Jesus has, and minister it to your spirit. Think about that!
When you know and walk with the Holy Spirit, He'll make your life beautiful, excellent, and full of glory. Some "preach" about Him but really don't know Him in truth.
Love Him dearly. Let it be your heart's most passionate desire to know Him more and more, and have Him revealed in your life. That's true Christianity: Christ —His anointing, person, character and righteousness— revealed in you!
Therefore, open your heart to Him. Yield yourself completely to Him in love and fellowship, and He'll show you new frontiers. He'll take off the limits, and position you for endless victories and to make lasting Kingdom impact.
