Asaph concluded this psalm by calling for God to judge the whole earth, not just Israel. The world then as now needed righteous judgment that only God, the righteous Judge, can provide. God's provision of Jesus Christ, to whom He has committed all judgment (John 5:22-30), was His answer to this petition.
The need for righteous judgment and the cry for it will continue until Jesus Christ reigns and judges. He will judge at various times in the future. For the Christian this will take place at the judgment seat of Christ (2 Cor. 5:10). For Tribulation saints and Old Testament saints it will be just after He returns at His second coming (Rev. 19:17-21; Isa. 26:19; Dan. 12:2). For unbelievers it will be at the great white throne judgment (Rev. 20:11-15).
