God didn't take Jonah out of service. He sent him back to Nineveh, saying, in effect, "Now go back to doing what I called you to do." If you've lost some major battles in life, you may be tempted to think that God is finished with you. It's not true. The problem is not that God gives up on his people. The problem is that his people give up on themselves.
Many believers, after getting knocked down by sin, decide to never get up. "What's the use? Why bother? I'll just stay down here from now on." You won't be let off quite that easy. God calls you to repentance. He calls you to confront your sin and deal with it His way. And after you have gotten back on your feet, God reminds you His Word remains the same. Trust God and obey Him even when you can’t trace His steps, you can always trust His heart.
