7 But the Lord sits enthroned forever;
he has established his throne for justice,
8 and he judges the world with righteousness;
he judges the peoples with uprightness.
9 The Lord is a stronghold for the oppressed,
a stronghold in times of trouble.
10 And those who know your name put their trust in you,
for you, O Lord, have not forsaken those who seek you.
11 Sing praises to the Lord, who sits enthroned in Zion!
Tell among the peoples his deeds!
12 For he who avenges blood is mindful of them;
he does not forget the cry of the afflicted.
13 Be gracious to me, O Lord!
See my affliction from those who hate me,
O you who lift me up from the gates of death,
14 that I may recount all your praises,
that in the gates of the daughter of Zion
I may rejoice in your salvation.
The validity of historically temporal and yet soteriologically eternal judgment in the first portion of this psalm is backed up by the exaltation of God. God’s sitting in judgment is affirmed by His judgment (v. 8). His kingship is demonstrated by His ruling. Our defense is His kingship. It is his judgment (v. 9). This defense in times of trouble is acquired by “trust” (aka faith).
It is because of these truths that God is to be praised. In complete knowledge of God is He to be praised. This includes His judgment on those who afflict His saints (v. 12-13). A fully Biblical Christian can’t help but sing of God’s judgment against sinners for it is our proclamation that God is in fact God.
