Micah 6:9

The Lord's voice crieth unto the city, and the man of wisdom shall see thy name: hear ye the rod, and who hath appointed it.

In this passage the reference is to that of the wickedness of Israel.

God had shown Israel how necessary it was that they should be obedient and do the right things. The Lord tells them in this verse to hear His rod (or parental reinforcement) when it is coming, even before they see it, and feel it, and to recognize the rod when it comes. To do so would be to be sensible and smart, as well it would be sensible to hear what counsels and what cautions the Lord speaks in regards to their activities. The voice of God is to be heard in the rod of God. Those who are dishonest in their dealings shall never be reckoned pure, whatever shows of devotion they may make. Fraudulent gains cannot be kept or enjoyed with satisfaction. What we hold closest we commonly lose soonest. Sin is a root of bitterness. As God's people they were to keep themselves in His love and honor Him, but rather, during their backsliding they did not recognize His rod, except for the few that were wise.

In our own lives, as well, when we fail to be obedient to the Lord His rod will come, and we will be wise to recognize such correction, and turn away from whatever disobedience we are currently practicing. Truly, none of us are sinless, but habitual sin is not a sign of repentence, and surely does not love or honor Him.
