Micah 7: the Lord will restore Israel

Micah says:

2 There’s not a decent person in sight.
    Right-living humans are extinct.

in contrast, Micah will trust in the Lord:

7
But me, I’m not giving up.
    I’m sticking around to see what God will do.
I’m waiting for God to make things right.
    I’m counting on God to listen to me.

He understands that the Lord listen to his prayers, so he is waiting on the Lord.
Perhaps Micah talks in name of the nation of Israel/Judah; but if Micah talks about himself, he acknowledges that he sinned. It is much easier to understand that Micah is talking in name of Israel:


8-10
Don’t, enemy, crow over me.
    I’m down, but I’m not out.
I’m sitting in the dark right now,
    but God is my light.
I can take God’s punishing rage.
    I deserve it—I sinned.
But it’s not forever. He’s on my side
    and is going to get me out of this.
He’ll turn on the lights and show me his ways.
    I’ll see the whole picture and how right he is.
And my enemy will see it, too,
    and be discredited—yes, disgraced!
This enemy who kept taunting,
    “So where is this God of yours?”
I’m going to see it with these, my own eyes—
    my enemy disgraced, trash in the gutter.

Although the Lord's people has been humiliated, the Lord will lift Israel among other nations. Micah prays:

14-17
Shepherd, O God, your people with your staff,
    your dear and precious flock.
Uniquely yours in a grove of trees,
    centered in lotus land.
Let them graze in lush Bashan
    as in the old days in green Gilead.
Reproduce the miracle-wonders
    of our exodus from Egypt.
And the godless nations: Put them in their place—
    humiliated in their arrogance, speechless and clueless.
Make them slink like snakes, crawl like cockroaches,
    come out of their holes from under their rocks
And face our God.
    Fill them with holy fear and trembling.

Micah trusts that the Lord is good, He is merciful, thus he writes:
    
18-20
Where is the god who can compare with you—
    wiping the slate clean of guilt,
Turning a blind eye, a deaf ear,
    to the past sins of your purged and precious people?
You don’t nurse your anger and don’t stay angry long,
    for mercy is your specialty. That’s what you love most.
And compassion is on its way to us.
    You’ll stamp out our wrongdoing.
You’ll sink our sins
    to the bottom of the ocean.
You’ll stay true to your word to Father Jacob
    and continue the compassion you showed Grandfather Abraham—
Everything you promised our ancestors
    from a long time ago.

So, Micah writes about the day of the Lord (where the Lord's people face punishment for their sins), he also writes about the restauration of the people of Lord, the people that the Lord loves and takes care.
