1 Peter 2:2
Like newborn babies, cry out for pure spiritual milk so that by it you may grow up in your salvation — the simile of infants (nēpioi) nursing on 'pure spiritual milk' (logikon adolon gala, rational/spiritual unadulterated milk) establishes that spiritual nourishment is essential to growth (auxanō) unto salvation. The metaphor suggests that believers, despite their new status as regenerate, remain infants requiring nourishment. The 'longing for' (epipothēsate) indicates active desire for the word.
