Jesus is God manifesting all authority and power.   

In order to see the Power Of The Holy Spirit manifested, the Word Of Truth must go forth in Faith.   

Prayer is often seen as a source of Power but it is merely a means by which we fellowship with our Lord bringing us to a point where we can speak and act on His behalf.   

When we meditate on the Word we allow our Lord to speak to us.   

When we speak in prayer we aught to reflect His Word.   

When we go forth in the name of Jesus we should do so in the authority of His Word by the power of His Spirit.
