WASHINGTON — Addressing a nation on an economic precipice, President Barack Obama asked worried Americans to pull together Tuesday night and declared reassuringly that the U.S. "will emerge stronger than before." Obama aimed to balance candor with can-do in his first address to a joint session of Congress.

"The weight of this crisis will not determine the destiny of this nation," Obama said. "Tonight I want every American to know this: We will rebuild, we will recover, and the United States of America will emerge stronger than before."

The comments were included in excerpts from the speech that were released early by the White House.

Set to address an ebullient Democratic congressional majority and an embattled but reinvigorated GOP minority as well as millions of anxious viewers at home, Obama was arguing that his still-unfolding economic revival plan has room for — even demands — a broader agenda including dramatic increases in health care coverage and wiser, "greener" fuel use.

"The answers to our problems don't lie beyond our reach. They exist in our laboratories and universities, in our fields and our factories, in the imaginations of our entrepreneurs and the pride of the hardest-working people on Earth," he said. "What is required now is for this country to pull together, confront boldly the challenges we face and take responsibility for our future once more."

Just five weeks after his inauguration, Obama wasn't charged with producing a formal State of the Union status report. But for all intents and purposes, that's what it was: a night for the president to sketch out his priorities in a setting unmatched the rest of the year.

The gallery was to include a special section hosted by first lady Michelle Obama in which guests were selected to serve as living symbols of the president's goals. Cramming the floor were to be the leaders of the federal government: Supreme Court justices, all but one Cabinet member — held away in case disaster strikes — and nearly every member of Congress.

Pre-speech, Wall Street was in a better mood than it had been in for days: Stocks were up after Federal Reserve Chairman Ben Bernanke said the recession might end this year.

Comments on Obama's address came in early from Republicans, hours before he had uttered a word.
