Then God saw their works, that they turned from their evil way; and God relented from the disaster that He had said He would bring upon them, and He did not do it. But it displeased Jonah exceedingly, and he became angry. Then the Lord said to Jonah, “Is it right for you to be angry?” Jonah 3:10-4:1, 4:4 NKJV

God’s question drew the clear distinction between man’s anger and God’s anger. God is not angered for human reasons. His anger is due to the falseness of idolatry and the viciousness of sin. The true goal of His anger is the salvation of the sinner. God looks for evidence of repentance and repudiation of evil ways, even unto the details.
