If we build a wall to protect ourselves from assailants, our enemies will bash and pound against it; they will punch the wall with their fists and kick it with their feet; they will smash rocks against it; they will whack at it with hammers, axes, and chisels; they will use shovels to dig holes under it, and ropes and ladders to climb over it; the wall may crack, and it may crumble, especially if it is built from weak material, or rests on an unsure foundation. But we build the wall anyway, for it is better to prepare for battle, than to sit defenseless against the inevitable onslaught of the enemy. Yet even if our wall is firmly built, wrought of steel and iron, and forged in the fires of adversity, it will still be utterly useless without guardians to stand watch over it, and protect it from our adversaries. Even the strongest wall can be easily toppled, if it is left undefended. Only by the vigilance of patriots, who are willing to stand guard and defend the wall at all costs, can we ever have any hope of security and freedom. Do not be the cold-hearted cynic who says the wall is useless because it cracks, but rather be the patriot who takes up arms, and drives the sword against those who do the cracking.
