But what then is this "righteousness of God"? In Israel's scriptures, to which Paul explicitly appeals in 3:21b ("the law and the prophets bore witness to it"), God's "righteousness" is not simply God's status of being morally upright. It is, more specifically, God's faithfulness to the covenant—the covenant not only with Abraham and Israel, but through Israel to the wider world.

God will justify us from our sins, but he will not justify the least sin in us: He is a God of purer eyes than to behold iniquity.

Reason fails to understand this, "for the natural man receiveth not the things of the Spirit of God." (I Cor. 2:14.) It therefore seeks righteousness in externals. However, we learn from the Word of God that there is nothing under the sun that can make us righteous before God and a new creature except Christ Jesus.

When God's righteousness is mentioned in the gospel, it is God's action of declaring righteous the unrighteous sinner who has faith in Jesus Christ. The righteousness by which a person is justified (declared righteous) is not his own but that of another, Christ.

Make no mistake, character is a supreme issue with God. But His approach is much different than ours. His righteousness/character is not built into us by our own efforts. It is developed when we quit striving and learn to abandon ourselves completely to His will.

It is only in the context of understanding something of God's character, of his righteousness and perfection, that we begin to understand the tremendous nature of saying that God truly is love, and his love has a depth, texture, fullness, and beauty to it that we, in our present state, can only begin to wonder at.

When the LORD your God has driven them out before you, do not say in your heart, “Because of my righteousness the LORD has brought me in to possess this land.” Rather, the LORD is driving out these nations before you because of their wickedness.

God is not satisfied with appearance. God wants the garment of justice. God wants his Christians dressed in love.

When New Testament authors stress that salvation is not arrived at by works, as first-century Jews, these authors are referring to works of the law. They are saying that God's righteousness does not come by external obedience to the law, as some Jews of their day supposed.

Put an end to the evil of the wicked, but establish the righteous, O righteous God who searches hearts and minds.

And the heavens proclaim His righteousness, for God Himself is Judge. Selah

There is every reason too to understand the display of that "righteousness" as connected with God's somehow rescuing the world from idolatry and sin, through Israel, in order to create a single worldwide family for Abraham. The actual arguments Paul advances on either side of our passage, in other words, strongly support a reading of dikaiosyn? theou and cognate ideas in 3:21—26 as "covenant faithfulness.
