Luther on Jesus becoming a curse for us

Commenting on Galatians 3:13

The doctrine of the gospel (which of all others is most sweet and full of most singular consolation) speaks nothing of our works or of the works of the law, but of the inscrutable mercy and love of God towards most wretched and miserable sinners. Our most merciful Father, seeing us to be oppressed and overwhelmed with the curse of the law, and that we could never be delivered from it of our own power, sent His only Son into the world and laid upon Him all the sins of all men, saying, be Thou Peter that denier; Paul that persecutor and cruel oppressor; David that adulterer; that sinner who did eat the fruit in Eden; that thief who hanged upon the cross; and be Thou that person who has committed the sins of all men: see therefore that Thou pay and satisfy for them.

–Martin Luther
