As we begin the 3rd chapter of Jonah, we again see God calling Jonah to go to Nineveh.  The calling is the same, but the messenger has been changed.  This is what the grace of God does.  It changes us, and equips us to rightly minister the grace of God to others.  As God was in the details of Jonah’s life for the good purpose of preparing him, so He is preparing all of those who love God and are called to His good purposes.
