Thus says the Lord: What wrong did your ancestors find in me that they went far from me, and went after worthless things, and became worthless themselves? They did not say, "Where is the Lord who brought us up from the land of Egypt, who led us in the wilderness, in a land of deserts and pits, in a land of drought and deep darkness, in a land that no one passes through, where no one lives?" I brought you into a plentiful land to eat its fruits and its good things. But when you entered you defiled my land, and made my heritage an abomination. The priests did not say, "Where is the Lord?" Those who handle the law did not know me; the rulers transgressed against me; the prophets prophesied by Baal, and went after things that do not profit (NRSV 2:5-8).
Thus saith the Lord, What iniquity have your fathers found in me, that they are gone far from me, and have walked after vanity, and are become vain? Neither said they, Where is the Lord that brought us up out of the land of Egypt, that led us through the wilderness, through a land of deserts and of pits, through a land of drought, and of the shadow of death, through a land that no man passed through, and where no man dwelt? And I brought you into a plentiful country, to eat the fruit thereof and the goodness thereof; but when ye entered, ye defiled my land, and made mine heritage an abomination. The priests said not, Where is the Lord? and they that handle the law knew me not: the pastors also transgressed against me, and the prophets prophesied by Baal, and walked after things that do not profit (KJV 2:5-8).
God clearly believes that he gave the people no reason to betray him. He's been pretty darn good to them over the years. And what happens? They never write, they never call—what's wrong with these kids today??
