Walls become firmer as more people despair of an end to the division. If we want to break down the walls, we need to first bring down the walls in our own hearts. A physical wall cannot be built in one morning or come down overnight, but the walls in the heart can come down all of a sudden.

Once we bring down the walls in our hearts we can start something small to help knock down the real walls. There is a Korean saying that “constant dripping wears away stone.” The raindrops continually dripping down from the roof make a hole in the stone terrace. If we do not give up our dream for peace and are persistent in our efforts, the real walls will come down eventually.

Korea’s demilitarized zone has become an accidental nature preserve that gives hope for a brighter future.
