The pure devotee has no actual chance to fall down

The devotee, in the beginning, may sometimes fall from the standard, but still he should be considered superior to all other philosophers and yogis. One who always engages in Kṛṣṇa consciousness should be understood to be a perfectly saintly person. His accidental nondevotional activities will diminish, and he will soon be situated without any doubt in complete perfection. The pure devotee has no actual chance to fall down, because the Supreme Godhead personally takes care of His pure devotees. [BG.9.34]
