Thus says the LORD concerning the prophets
Who make my people stray;
Who chant "Peace"
While they chew with their teeth,
But who prepare war against him
Who puts nothing into their mouths:
"Therefore you shall have night without vision,
And you shall have darkness without divination;
The sun shall go down on the prophets,
And the day shall be dark for them.
So the seers shall be ashamed,
And the divines abashed;
Indeed they shall all cover their lips;
For there is no answer from God."
But truly I am full of power by the Spirit of the LORD,
And of justice and might,
To declare to Jacob his transgression
And to Israel his sin.
God's talking to the 'false prophets' in the beginning here. These are people who will prophesy for people who feed them, and will attack those who don't feed them. So God was going to cut off their visions. He would put an end to these false prophets who terrorized His people.
But Micah, God's real prophet, was filled with God's power, and that of His Spirit. He was filled with justice and might, just to tell Jacob and Israel (the two parts of the Jewish nation) what they were doing wrong, to strengthen their relationship with God.
Notice how in this case, God isn't weakening those who did wrong, He's weakening those who lead them to do wrong. These people are taking advantage of others. So God is going to take care of them.
But not only does He weaken those who lead His people astray, He strengthens those who bring His people to Him. If we bring people to God, we will be like Micah: filled with the power of God, His justice, and His might, to help others understand Him better. If we dirty God's name, by leading others astray, He'll make sure we stop.
In His Service,
