Since God is the creator of everything that exists and it is His world, who else would be just in holding the office of judge over the world? Who else would have the authority to administer justice by trying cases concerning the world in relation to biblical truths? Let's let Scripture answer this question. God is the ultimate Judge of all the earth.
(Gen 18:25; Isa 33:22; James 4:12).
As God’s representative, Christ functions as judge as well
(John 8:16; Jas 5:9; 1 Peter 4:5).
As is frequently the case with biblical truths, the Christian’s role in exercising judgment on others is found in a tension between warnings to avoid judging others and admonitions concerning how best to judge others. Christians are forbidden to judge others when such judgment entails intolerance of another’s sin coupled with blindness of one’s own sin
(Matt 7:1-5; Luke 6:37; John 8:7; Rom 2:1-4)
or when human judgment impinges on God’s prerogative as judge
(Rom 14:4; 1 Cor 4:5;Jas 4:11-12).
Instructions on proper exercise of judgment include: the call to judge reputed prophets by their fruits
(Matt 7:5-17);
encouragement for Christians to judge what is right for themselves and thus avoid pagan law courts
(Luke 12:57-59; 1 Cor 6:1-6);
and instructions regarding church cases
(Matt 18:15-20). 1 Cor 5:3-5
illustrates the function of a church court. Listed below are general references to answer if God is a just judge;
A personal characteristic of care for the needs of others. The biblical concept of mercy always involves help to those who are in need or distress.
Such help covers a broad range, from assistance in finding a bride to God’s forgiveness of sin. A wide vocabulary is employed in the original languages to express these concepts, and an even wider vocabulary is found in English translations.
God's compassion and love are expressed in a variety of ways that lead up directly to the new testament doctrine of divine fatherhood. He folds Israel in his arms as a shepherd his lambs
(Isa 40:11).
His scattered children are his sons and daughters whom he redeems and restores
(Isa 43:5-7).
In wrath for a moment he hides his face, but his mercy and kindness are everlasting
(Isa 54:8).
Greater than a mother’s tenderness is Yahweh’s love for Israel
(Isa 49:15;66:13).
