A few years ago there was a very popular song entitled, "I Got The Power".  This is a phrase I believe every saint ought to confess.  It will be your understanding of power that will give you the results you seek in bringing forth manifestation.
 
It must also be understood that God is ready for the Body of Christ to reveal its glory to this world.  This, however, cannot be done if the church operates powerless.  God uses His power to demonstrate His Glory; it is only then that His Kingdom is built.
 
In 1 Chronicles, we see David is a king which means he had power and authority.  David accomplished much in his life.  He slained a bear, a lion and a giant.  He also took 400 men and trained them to be the world's greatest army of its time.  Yet, David knew and understood that all power, both in heaven and earth, comes from God.  David knew this and was not ashamed to profess and bless God Almighty before his entire congregation.  David was great and powerful because of God.
 
If we do not have any power, we cannot accomplish anything.  What we must do is come to an understanding of power and how to use it.  The definition of power is the capacity or ability to do something of accomplishment.  Power is your ability to do work.
