The Programmer has made things to operate the way they do so that non-believers would have to freely choose to exert a reasonable amount of effort to leave the lesser kingdoms of programmed entities and approach His realm.
Out of all the men in the world, The Programmer has selected a tiny handful to act as His emissaries. He has given them special powers. Earthly ambassadors have the power to conclude treaties and issue passports. A parish priest may make peace between a soul and He Who Programmed that soul and may issue the necessary permits for that soul to get past the otherwise impassible guards and gates of the Heavenly Kingdom.
