"Ever since Adam disobeyed the Word of God, however, all his 
descendants
have been unrighteous in their ways. God’s righteous judgment has been
that “there is none righteous, no, not one” (Romans 3:10).
Thus, a truly righteous Judge would not only have to consign Sodom to destructive “brimstone and fire from the LORD” (Genesis 19:24) but every one of us as well “into the lake of fire” (Revelation 20:15).
But God, being not only the righteous Judge but also “a faithful Creator” (1 Peter 4:19), had a plan whereby He could “declare his righteousness for the remission of sins that are past” and both “be just, and the justifier” of those who had been lost sinners (Romans 3:25-26). “God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh” (8:3).
So, Christ has been “made unto us...righteousness” (1 Corinthians 1:30). "
