why is Good Deeds Everyman's only faithful companion in the play Everyman?

Good Deeds seems the only one capable of leading everyman to his final judgment. Good Deeds is really a personification of what we hold as "godly" in human nature. Good Deeds is empathetic, love, altruistic and patient. It is the personification of the perfect nurturing mother-figure. After man has crossed into the "undiscovered country" it is only his past deeds that he be judged on. Good Deeds hence stays with Everyman echoing into eternity. If Everyman heeds her advice, she is faithful.
