"A Kingdom Divided” is a series on Sharper Iron that goes through 1-2 Kings. The division in the kingdom of Israel in this part of history was greater than a matter of north and south. The biggest division was between the people and their God. Yet even as the people rebelled against the LORD as their King, still He remained faithful to call them back to Himself through His prophets, working through history to send the good and grac...
