This thanksgiving psalm anticipates a victory when God as Judge would destroy the wicked and establish the righteous. Psalm 75:1 (Constable's notes)

We give thanks to you, God;
we give thanks to you, for your name is near.
People tell about your wondrous works.
-Psalm 75:1

This thanksgiving psalm anticipates a victory when God as Judge would destroy the wicked and establish the righteous. (See 1 Sam. 2:1-10, Luke 1:50-53).

God is near to His people and has performed wondrous works.

God judges when He decides the time is right.

He judges fairly.

His judgment can devastate the world, but He sustains it nevertheless.

The wicked are called to repent.

No help from any direction will deliver the ungodly when God judges them.

As Judge, God forces His enemies to drink from the cup that determines consequences.

He forces them to drink all the wine of judgment that He has prepared for them (cf. 60:3; Isa. 51:17-23; Hab. 2:16).

They cannot escape doing so or the consequences of doing so at His appointed time.

In some nations kings made convicted criminals drink poisoned wine.

This inspiring psalm pictures Yahweh in His role as Judge of all the earth.

Its perspective is toward that day when He will act in justice for His people.

This day will inevitably come, and we need to keep it in view since God waits to judge.

The Judge of all the earth will do justly (Gen. 18:25).
