The engraving on this key reminds us of two common but complex Christian commands: the love for God and the love for our neighbors. A successful life opens up to anyone who keeps these commands. If one behaves in accordance with these maxims one will come to know the answer to the great question of existence: “Why am I here on earth?” One does not only live for oneself, but rather opens up for one’s fellow human beings and realizes himself to be one part of all creation.
