You have a correct answer. It does show that Lincoln used the declaration to show to the people his faith in the war. That he wishes for America to return back to scratch to its ideals of peace and freedom.
<em>Why does Lincoln allude to the Declaration of Independence here?</em>
<em>The correct answer is, “To express hope that the current government will be reformed.”</em>
<em>Lincoln expresses hope when he says that the dead that is to come will not be in vain, because all that dead will help this nation to have a new birth of freedom. In addition, he says that a democratic government will not perish. A reformed government will hold the truths that all men are created equal, that they have the right to life, liberty and the pursuit of happiness. This reformed government will endure under the consent of the governed, not by the slavery of the governed. The people have the right to abolish the forms to which they are accustomed.</em>
