President Obama spoke Sunday to a grieving nation following his visit with survivors of the Colorado theater massacre and family members of the 12 dead, promising that their strength and courage will long outlive the infamy of the shooter.

“The perpetrator of this evil act has received a lot of attention over the past couple of days,” the president said in a speech at the University of Colorado Hospital. “What will be remembered are the good people impacted by this tragedy.”

The brief speech was both spiritual and presidential, with Obama quoting scripture, thanking doctors and first-responders, vowing the shooter would feel the “full force of the justice system” and calling for the country’s leaders to “do something about this senseless violence.”

The gunman killed 12 people and wounded 58 others during a midnight showing of the Batman movie “The Dark Knight Rises” at the Century 16 multiplex in Aurora, Colo., a Denver suburb.

Obama said that scripture states God “will wipe away every tear from their eyes and death shall be no more. Neither shall there be mourning, nor crying, nor pain.”
