This is serious power. There is a concentration of effort. All the resources are drawn together in a common cause. No way anyone's mind could be wandering to next week's grocery list. Time, talent, treasure are all put into the service of God.
Nothing is left out.
All is concentrated and consecrated. Each one does what he or she can, and no one would consider not pulling a proper share of the load. Love the Lord your God with all your strength. No holding back. Now, up to this point, those folks on the road who were listening to Jesus banter back and forth with the local rabbis would not have been surprised by anything they heard.
