In Jonah 3, we find that God did not give up on Jonah or on the people of Nineveh, which encourages us to believe that he has not given up on us either.  Upon hearing Jonah’s preaching of impending destruction, the Ninevites surprised everyone by believing God and turning from their sins to him.  According to Jesus, they became an example for later generations of what it means to repent.  God’s response to them is also an example of how he treats all who turn from sin to him with faith.
