John 1:16 - And of his fulness have all we received and grace for grace.
Most Christians believe God can do anything but experience very little. They believe that God can release His power in answer to prayer, but whether something comes to pass or not depends on their performance (ie. being holy, speaking right, studying the word. tithing, avoiding strife, etc).
This view short-circuits God's power because their focus is on what they need to do instead of what Christ has already done. They think God's power is out there somewhere, and they must do things in order to obtain it!
The truth is, when we were born again, God put His power, anointing, victory, joy, peace -- everything -- in us in abundance. The only reason they weren't manifest in our soul and body is our unrenewed mind.
