“Remember how the Lord your God led you all the way in the wilderness these forty years, to humble and test you in order to know what was in your heart, whether or not you would keep his commands.
He humbled you, causing you to hunger and then feeding you with manna, which neither you nor your ancestors had known, to teach you that man does not live on bread alone but on every word that comes from the mouth of the Lord.
He causes us to hunger only to satisfy us with himself and teach us that true life is found in Him and His word, not in wealth, success, marriage, etc.
He leads us through the dark valleys to humble us, discipline us, to strip us of our idols, and most importantly, to show us where true life is found, even through the pain and suffering.
