When you were a child, you came to the dinner table, knowing that your parents would have food for you there. This child-like faith went for years, for all of us, and it was not until much later that we all learned what that provision cost. All we knew was that parents feed their children. We are born knowing this. No one has to teach a newborn how to cry for milk, or where to look for it.
The Word tells us that we, like newborn infants, should desire the pure milk of the Word, now that we have tasted that the Lord is good. Two things drive us. Like all who are born alive, we are born hungry. There is an instinct within us, an instinct that shows us born alive within the kingdom; we seek out the food of the Word. This of course applies to the Word of God preached, but it also applies to the Word of God eaten, the Word of God in a cup. We have an instinct that drives us here.
But Peter tells us that children also develop an affection for the Word through their experience—now that you have tasted that the Lord is good, he says. You have been coming to the Lord’s table on a weekly basis for years now. Try to imagine for a moment what it would be like to go back to what many of us experienced for years, when the Lord’s Supper was observed periodically, rarely, or in some cases, never.
The Lord’s children should be characterized by many things, but this should be high on the list—the Lord’s children clamor for food.
