Though scoffers arise and cast aspersions towards God and His promise to reward the righteous and punish the wicked, God is not slack in keeping His word. When He chooses the proper time, He will judge uprightly; the earth and all its inhabitants will be powerless to resist (Psalm 75:2-3).
Because of this immutable fact, Psalm 75:4-8 offers the following counsel: “I said to the boastful, ‘Do not deal boastfully,’ and to the wicked, ‘Do not lift up the horn. Do not lift up your horn on high; do not speak with a stiff neck.’ For exaltation comes neither from the east nor from the west nor from the south. But God is the Judge: He puts down one and exalts another. For in the hand of the Lord there is a cup, and the wine is red; it is fully mixed, and He pours it out; surely its dregs shall all the wicked of the earth drain and drink down.”
The Lord is not slack concerning His promises. Because He is longsuffering toward all, not willing that any should perish, all the wicked need to repent while they can and all the righteous need to persevere.
God’s final word—His sure testimony—on the matter is “All the horns of the wicked I will also cut off, but the horns of the righteous shall be exalted” (Psalm 75:10).
