Approved devotee
Srimad-Bhagavatam
SB Canto 3
SB 3.14.44-45, Translation:
The learned Kaśyapa said: Because of your lamentation, penitence and proper deliberation, and also because of your unflinching faith in the Supreme Personality of Godhead and your adoration for Lord Śiva and me, one of the sons (Prahlāda) of your son (Hiraṇyakaśipu) will be an approved devotee of the Lord, and his fame will be broadcast equally with that of the Personality of Godhead.
