Blessing over Hands

Berakhot ... the Hebrew thought for blessing when used as the "Blessed are you Oh Lord God King of the universe... implies the question ?May I have permission to enjoy this?? as well as Thank you for the provision.
Prayer... implies that I am the one that is changing as the result of this petition..
This is important because we typically pray with the intent to "Get God to do something or change something!!!!"
Torah portion this week promises that God will remove the obstacles (enemies) in the land a little at a time. Seems to indicate that we will have to grow to be able to take over the land (territory.) In prayer we simultaneously change a little to correspond to the the difference between before and after we pray & then we "authorize the forces of our King to move in behalf of us or the ones for whom we pray making creative changes as are necessary to complete the burden of our request."
Faith is that spiritual force that "carries our hope" over the time lapse between the prayer spoken and the prayer actualized.

Putting it altogether we have the thought that the heart felt (emotionally heated) prayer of the righteous man(person) avails (is powerful to accomplish the task) much.

Exodus 23

29 I will not drive them out from before thee in one year; lest the land become desolate, and the beast of the field multiply against thee.

• 30 By little and little I will drive them out from before thee, until thou be increased, and inherit the land.
  
• 31 And I will set thy bounds from the Red sea even unto the sea of the Philistines, and from the desert unto the river: for I will deliver the inhabitants of the land into your hand; and thou shalt drive them out before thee.
