Why should posterity revere the saints? It is because all the stories of the struggle for goodness are concentrated in their hearts. In order to achieve a purpose of goodness, we should make efforts through their foundations. Otherwise, we cannot connect with the path leading to the purpose. Although they are fallen posterity, many people cherish the saints and seek to follow in their footsteps, for the human heart is connected to the heavenly heart. This is a natural pursuit of original value. (17-268)

Who will remain in history? People who died for the sake of an individual cannot be revered by people and remembered in history.

The ones who died for a family will be revered by many individuals. The ones who died for their nation through a religion, however, will be revered by all the families. Furthermore, the ones who died for the sake of the world in the name of religion will be revered by the nations who pursue this religion. (27-173)

No saint has been welcomed in his or her historical age. Only a hundred or thousand years after their deaths, when their bones have changed into ashes, do they become historic objects of reverence. That has been the path of the saints so far. (127-33)
