Read the excerpt from paragraph 3.
Our Constitution is a remarkable, beautiful gift. But it's really just a piece of
parchment. It has no power on its own. We, the people, give it power
with
our participation, and the choices we make. Whether or not we stand up for
our freedoms. Whether or not we respect and enforce the rule of law. America
is no fragile thing. But the gains of our long journey to freedom are not
assured.
How does Obama create cohesion in this paragraph?
