This is a serious Psalm. It confronts the rebellion and pride and self-deception surrounding us in the world today. It brings us back to the reality of God and follows up on the truth we saw in Psalm 93:1, that The Lord reigns, he is robed in majesty; the Lord is robed in majesty and armed with strength.
I suggest, before we consider it in more depth, to begin with, read the first 11 verses below and then meditate on these verses as you listen to the song based on this Psalm from the group called Sons of Korah found at the link below:
The Lord is a God who avenges.
O God who avenges, shine forth.
2 Rise up, Judge of the earth;
pay back to the proud what they deserve.
3 How long, Lord, will the wicked,
how long will the wicked be jubilant?
4 They pour out arrogant words;
all the evildoers are full of boasting.
5 They crush your people, Lord;
they oppress your inheritance.
6 They slay the widow and the foreigner;
they murder the fatherless.
7 They say, “The Lord does not see;
the God of Jacob takes no notice.”
8 Take notice, you senseless ones among the people;
you fools, when will you become wise?
9 Does he who fashioned the ear not hear?
Does he who formed the eye not see?
10 Does he who disciplines nations not punish?
Does he who teaches mankind lack knowledge?
11 The Lord knows all human plans;
he knows that they are futile.
