What can account for the way in which “that great city” (Jonah 3:2)  made such a change?  It is because God worked in their hearts.  God worked through the preaching of His Word to change the hearts of the people.  This repentance, we are told, extends even to the king of Nineveh (Jonah 3:6-7).  

What is your attitude to the preaching of God’s  Word?  Are you receptive to it?  Have you recognized it as the Word of God which is authoritative and powerful?  Are you grateful for the grace of God in giving us His Word?  This is the Word that presents to us the message of the Gospel.  God has not left His people without hope or without a Word from Him.
