God has may ways to speak to people. In Micah 1, God's uses the names of some towns in Judah to be a prophetic witness to His people.
In Micah 2, through His prophet, God speaks out against wicked people who devise schemes to oppress others in the quiet of the night, while they lay on their beds. These plot evil during the night and then carry out their evil plans when the sun comes up.
God is against such wickedness and will bring down trouble upon the schemers themselves. It is a terrible thing to have the Lord come against you. However, even should such a terrible thing happen, God's judgment is nevertheless still meant for our good because through it God's desire is for those upon whom trouble comes to turn from their wickedness and turn to God. The work of God's prophets was often to warn the people of the disaster that would come their way if they did not repent. The trouble, however, was that too few people were willing to listen to the prophet. They didn't mind listening to "prophets" who told them what they wanted to hear, but listening to prophets who spoke the truth was anothe thing altogether.
Reproach cannot be turned back if a warning is not given in the first place. If we know Jesus Christ and know that God's desire is for us to proclaim Christ and the Truth of who God is, we have got to speak out - even though it may not be popular. The world needs to hear the Truth. If believers in Jesus don't speak it out, then who will?
