If you haven't yet, read part 1 , part 2 , and part 3 . The history of Israel was a rough ride. You can read all the good, the bad, and the very ugly in the books of 1 & 2 Kings. God made a great promise to King David, but because of the foolishness of David’s own grandson, Rehoboam, the kingdom divided into two distinct nations – the 10 Northern Tribes formed the nation of Israel (also known as Ephraim), and the 2 Southern Tribes of Judah and Benjamin formed the nation of Judah. The monarchies of these respective kingdoms were riddled with wickedness and sin. There was no one to keep the kings in line. They were answerable to no one, seemingly above the Law. So God raised up a school of Prophets who would be his mouthpiece to the kings. Samuel, Nathan, Elijah, Elisha, Jeremiah, Amos – all these men and more were God’s means of speaking truth to the powers that be. But none would be more well-known or have a greater lasting impact than the priest-turned-prophet Isaiah.
