Righteousness as Morality and Holiness
In Isaiah 5:16 “Righteousness” (hq")d'c.) refers as “God.” So
“Righteousness is holiness expressed in moral principles; justice is the application of
the priciples of righteousness. Both justice and righteousness are the outshining of holiness.”28
For J. Alec Motyer, Righteousness is a reflection of morality. “Righteousness is the glory of Zion. Again righteousness is God as it is a Divine’s holiness.”29 Moreover, Righteousness is morality, a good lifestyle in accordance with God’s description. Isaiah 59:14 mentioned, “Justice and righteousness (hq")d'c.) is a moral practice arising out of a moral principle.”30
According to KyeSang Ha, Yahweh is “not constrained by moral weakness due to his own sin or inadequate wisdom to apply justice and kindness.” God, as the divine King, Lawgiver and Judge (cf. Isa 33:22), is “morally responsible for his judgments, including his forgiveness of guilty people.”31
Again in Isaiah 9:7 “Righteousness” (hq'd'c.) as “the moral foundation will be justice and righteousness and the lost glories of Zion will be restored. Not only so, but the divine holiness will be perfectly manifested in true procedures (justice) which reflect righteous principles.”32
For political sense, Righteousness is “the outworking of holiness in the application of righteous principles of world government (Isaiah 5:16).”33
In Isaiah 28:17 “Righteousness” (hq'd'c.) mentioned as “Justice and righteousness either describe the quality of life the Lord desires in his believing people and to which he will apply his measuring line and his plumb-line (the tests of horizontal and vertical exactitude), or else they describe how the Lord will act in judgment against the scoffers.”34 These two meanings are obviously complementary.
Motyer believes the expression of righteousness is justice and holiness. In origin, righteousness is rooted in God, divine holiness. God is the only one perfect righteousness.
Therefore, in order to have freedom, we need to be righteous. Righteousness is God’s moral.
