Parched?
Going even a day without water starts damaging effects on our bodies that, left unremedied, will take a downward spiral until you either give your body the life-giving liquid or death overtakes you. Likewise, we don't deprive bodies of food for extreme periods of time for the same reasons.
Can we can go a day without the "food" and "water" of God's truth and not damage our spiritual bodies? Keeping in touch with God through prayer and reading the Bible is to our souls what food and water are to our bodies. Life is hard enough without trying to do it in our own strength.
