"It is for us the living ... to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced," Abraham Lincoln said in the Gettysburg Address, speaking of the responsibility of the living to carry on the mission of those who died in battle, and people today can do no more to honor Dr. Martin Luther King Jr. than to carry on his mission of a colorblind society, Rep. Chet Edwards, D-Waco, said Monday.Edwards was the featured speaker at a program honoring King sponsored by the Temple chapter of the National Association for the Advancement of Colored People at the Wayman Chapel African Methodist Episcopal Church."It is not our words today, but our actions tomorrow," that will see King's dream come true, Edwards said. "Let us not rest until we have true equality. In big ways and in small ways, let us work together for national unity."Edwards said he had thought about what lessons could be learned from King's life and philosophy about the tragedy caused in the Sept. 11 terrorist attacks. by Anna Foster
