Why can't I express God's power as a believer

We have seen how a gentle young man can suddenly become violent immediately an evil spirit possesses him, he becomes very strong unstoppable and he will begin to express all the abilities of that spirit.

 The truth is that spirits are powerful but their powers can only be expressed on earth through partnership with a human body.

_(Matthew 12:45  Then goeth he, and taketh with himself seven other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is worse than the first. Even so shall it be also unto this wicked generation.)_ 

The Spirit of God likewise, the Holy Spirit cannot work on earth without a man. The holy spirit has the power for healing the sick, raising the dead, and can do all things but he needs partnership with a yielded body.  Believers with the Holy Spirit cannot express the abilities of the Holy Ghost....why?

The evil spirit compels people they posses to do things but the holy spirit is not a compelling spirit. It only guides men

 _(John 16:13  Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.)_

 All that the Holy Spirit needed is that you allow him to lead you by submitting to him, obeying his voice, and doing His will. This is how you can come into expression of all the abilities of the Holy Ghost In You.

The holyghost is always available for believers, but believers have refused to make themselves available for his expression.

Constant fellowship with the spirit of God gives you more knowledge of his person. Any believer who express God's power tangibly is yielded and obedient. Another thing is the consciousness of God's power, you can't walk in it if you don't aknowledge it.
