Jonah (6): Jonah preaches to the Ninevites (Jonah 2.10 - 3.10)

Jonah preaches to the Ninevites. What did he say? How was it that they all repented and turned to God from the greatest to the least? If God gave wicked Nineveh a great revival, can He not do the same in our communities today? We also discuss the theological issue raised by the fact that God relented or changed His mind concerning His declaration that He would destroy Nineveh. If God is perfect and so cannot change, how could He change His mind concerning what He would do with Nineveh?
