It takes a childlike heart to feel the promptings of the Spirit, to surrender to those commands, and to obey. That is what it takes to be nourished by the good word of God.
We treasure the word of God not only by reading the words of the scriptures, but by studying them. We may be nourished more by pondering a few words, allowing the Holy Ghost to make them treasures to us, than to pass quickly and superficially over whole chapters of scripture.
