A humorous greeting card showed a grotesquely thin cow wandering in a barren desert. The skinny cow was meant to illustrate “where nonfat milk comes from.” The logic of the cartoon, of course, is entirely unscientific. Nonfat milk is not produced by nonfat cows!

The idea, however, reminds me of D. L. Moody’s comment: “Most people talk cream and live skim milk.” If our hearts are spiritually underfed, we will produce “skim-milk” Christianity. Our lips may utter spiritual-sounding words in prayer, worship, and conversation, giving the impression of “top-grade cream.” But the reality is revealed by what is consistently produced in our lives.

How can we live cream and not just talk it? David grappled with this in Psalm 19. In verses 12 and 13 he was honest with himself and with God when he asked to be cleansed from secret faults and presumptuous sins. Beyond forgiveness, David knew he needed God’s continuing strength and help to harmonize his walk with his talk. So he earnestly prayed, “Let the words of my mouth and the meditation of my heart be acceptable in Your sight, O Lord” (v.14).

In our walk, let’s move from skim milk to cream by being open, honest, and prayerful.
