Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 54

Sanskrit:

दिष्‍ट्या गृहेश्वर्यसकृन्मयि त्वयाकृतानुवृत्तिर्भवमोचनी खलै: ।सुदुष्करासौ सुतरां दुराशिषोह्यसुंभराया निकृतिं जुष: स्‍त्रिया: ॥ ५४ ॥

ITRANS:

diṣṭyā gṛheśvary asakṛn mayi tvayākṛtānuvṛttir bhava-mocanī khalaiḥsu-duṣkarāsau sutarāṁ durāśiṣohy asuṁ-bharāyā nikṛtiṁ juṣaḥ striyāḥ

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:

Śrīla Jīva Gosvāmī 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 ācārya 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.
