TEXT 31
अहो बतात्यद्भुतमेष रक्षसा 
  बालो निवृत्तिं गमितोऽभ्यगात् पुनः । 
  हिंसः स्वपापेन विहिंसितः स्वलः 
  साधुः समत्वेन भयाद् विमुच्यते ॥३१॥
aho batāty-adbhutam eṣa rakṣasā 
  bālo nivṛttim gamito 'bhyagāt punaḥ 
  himsraḥ sva-pāpena vihimsitaḥ khalaḥ 
  sādhuḥ samatvena bhayād vimucyate
aho—alas; bata—indeed; ati—very much; adbhutam—this incident is wonderfully astonishing; eṣaḥ—this (child); rakṣasā—by the man-eating demon; bālaḥ—the innocent child Kṛṣṇa; nivṛttim—taken away just to be killed and eaten; gamitaḥ—went away; abhyagāt punaḥ—but He has come back again unhurt; himsraḥ—one who is envious; sva-pāpena—because of his own sinful activities; vihimsitaḥ—now (that demon) has been killed; khalaḥ—because he was envious and polluted; sādhuḥ—any person who is innocent and free from sinful life; samatvena—being equal to everyone; bhayāt—from all kinds of fear; vimucyate—becomes relieved.
TRANSLATION
It is most astonishing that although this innocent child was taken away by the Rākṣasa to be eaten, He has returned without having been killed or even injured. Because this demon was envious, cruel and sinful, he has been killed for his own sinful activities. This is the law of nature. An innocent devotee is always protected by the Supreme Personality of Godhead, and a sinful person is always vanquished for his sinful life.
PURPORT
Kṛṣṇa conscious life means innocent devotional life, and a  sādhu  is one who is fully devoted to Kṛṣṇa. As confirmed by Kṛṣṇa in  Bhagavad-gītā
