Taste is such a vivid sense. Watch the face of baby who bites into a lemon. Watch as someone takes a big sip of iced tea that they thought was 
sweet (and it wasn’t).
Eating is essential to life. This is especially true in the life of a child. The only way to properly grow is to eat. And, eating is much more desirous when the food tastes especially good.
In First Peter 2, the apostle urged his fellow Christians, “as newborn babes,” to “desire the pure milk of the word” (2:2). Why should they desire to eat? “That you may grow thereby” (2:2). But, what could really enhance his craving to eat God’s Word, so that he could grow? The taste! The taste would determine the craving, which would determine the amount one would eat, which would determine growth. So, what is there to taste? “Indeed you have tasted that the Lord is gracious” (2:3). The goodness, kindness and graciousness of the Lord (in our past, in our present and in our future) ought to create an insatiable craving in us for the Lord!
