Near the end of his inaugural address Tuesday, Obama spoke of the need for every American to recognize duties to themselves, their nation and the world.
He calls it "the price and the promise of citizenship." And he says it's also the source of the nation's confidence - that "God calls on us to shape an uncertain destiny."
He told the crowd, "There is nothing so satisfying to the spirit, so defining of our character, than giving our all to a difficult task."
President Barack Obama is telling the world's Muslims that his administration will be looking for a "new way forward, based on mutual interest and mutual respect."
And he's warning leaders around the globe who try to encourage conflict and "blame their society's ills on the West" that their people will judge them on what they build, not what they destroy.
In his inaugural address, Obama also pledged broader engagement in the world. Saying the people of the world should know that America is a friend of all who seek "a future of peace and dignity," Obama vowed that the U.S. is "ready to lead once more."
He's also pledging to "work alongside" the people of poor nations to make "farms flourish and let clean waters flow."
