Of Justification | The Lutheran Church - Missouri Synod: "17. Holy Scripture sums up all its teachings regarding the love of God to the world of sinners, regarding the salvation wrought by Christ, and regarding faith in Christ as the only way to obtain salvation, in the article of justification. Scripture teaches that God has already declared the whole world to be righteous in Christ, Rom. 5:19; 2 Cor. 5:18-21; Rom. 4:25; that therefore not for the sake of their good works, but without the works of the Law, by grace, for Christ's sake, He justifies, that is, accounts as righteous, all those who believe, accept, and rely on, the fact that for Christ's sake their sins are forgiven. Thus the Holy Ghost testifies through St. Paul: 'There is no difference; for all have sinned and come short of the glory of God, being justified freely by His grace, through the redemption that is in Christ Jesus,' Rom. 3:23, 24. And again: 'Therefore we conclude that a man is justified by faith without the deeds of the Law,' Rom. 3:28."
KJV Romans 4:23 Now it was not written for his sake alone, that it was imputed to him; 24 But for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead; 25 Who was delivered for our offences, and was raised again for our justification.
Here it is in your beloved Reformed NIV:
NIV Romans 4:23 The words "it was credited to him" were written not for him alone, 24 but also for us, to whom God will credit righteousness-- for us who believe in him who raised Jesus our Lord from the dead. 25 He was delivered over to death for our sins and was raised to life for our justification.
