1 Peter 2:2-3

2 like newborn babies, long for the pure milk of the word, so that by it you may grow in respect to salvation, 3 if you have tasted the kindness of the Lord.

Here Peter is comparing new converts, in their spiritual lives, to new infants. I’m not sure how it is with infants in regard to their feeding practice. I assume that they naturally long for milk from their mother. But maybe not. Maybe they have to be coaxed or enticed to taste of the sweet milk. And the more they suck and taste, the more they long for it. Since it seems to be an imperative that a new believer long for the word, it may be that it is not a natural thing. We must develop a taste for it and discover His kindness—so that we may long for it and then “grow in respect to salvation.” That is, that we learn all about our salvation and grow into its fullness.
