“Where Christ is truly seen, there must be full and perfect joy in the Lord, with peace of conscience, which thus thinketh: Although I am a sinner by the law, and under condemnation of the law, yet I despair not, yet I die not, because Christ liveth, who is both my righteousness and my everlasting life. In that righteousness and life I have no sin, no fear, no sting of conscience, no care of death. I am indeed a sinner as touching this present life, and the righteousness thereof… But I have another righteousness and life, above this life, which is Christ the Son of God, who knoweth no sin, no death, but is righteousness and life eternal…
He that strayeth from this Christian righteousness, must needs fall into the righteousness of the law; that is to say, when he hath lost Christ, he must fall into the confidence of his own works. But… when I have Christian righteousness reigning in my heart… I do good works, how and wheresoever occasion arise… Whosoever is assuredly persuaded that Christ alone is his righteousness, doth not only cheerfully and gladly work well in his vocation, but also submitteth himself… to all manner of burdens, and to all dangers of the present life, because he knoweth that this is the will of God, and that this obedience pleaseth Him.”
Martin Luther
"It is because of him that you are in Christ Jesus, who has become for us wisdom from God- that is our righteousness, holiness and redemption." 1 Corinthians 1:30
