Srimad Bhagavatam Canto 10, Chapter 60, Text 54

SB 10.60.54

distya grhesvary asakrn mayi tvaya
 krtanuvrttir bhava-mocani khalaih
su-duskarasau sutaram durasiso
 hy asum-bharaya nikrtim jusah striyah
 
Translation: 
 
Fortunately, O mistress of the house, you have always rendered Me faithful devotional service, which liberates one from material existence. This service is very difficult for the envious to perform, especially for a woman whose intentions are wicked, who lives only to gratify her bodily demands, and who indulges in duplicity.
 
Purport: 
 
Srila Jiva Gosvami poses the following question: Since devotional service easily awards one liberation, isn’t it possible that everyone will be liberated and the world will no longer exist? The great acarya answers that there is no such danger, since it is very difficult for envious, duplicitous, sensuous persons to faithfully serve the Supreme Personality of Godhead, and there is no shortage of such people in the world.
