So let us not be petty when our cause is so great. Let us not quarrel amongst ourselves when our Nation's future is at stake.
Let us stand together with renewed confidence in our cause - united
in our heritage of the past and our hopes for the future - and
determined that this land we love shall lead all mankind into new
frontiers of peace and abundance.
