What do we crave? I have asked others and considered how often I eat, the needs and cravings, during the day, and it is often. And our spiritual body? 
The reality is we just don’t think about that, but it is real and it needs to be sustained just like our physical body. We need to read the Bible as we can’t depend on what we hear in a Sunday sermon or a weekly Bible study. God wants to speak to us with His words directly to our spiritual body so we can grow in our salvation and be sanctified. Babies are precious… we can see their smiles, but babies screaming out of need is unbearable… would our spiritual beings be heard screaming for pure milk? 1 Peter 2:2
