Consider the price of this ransom, look carefully at this captive. He is the Son of God who is greater than all creation. How will you respond when you hear that such a priceless ransom was paid for your sins? Will you still want to offer your works done under the law? What is the works of all men, the suffering of the martyrs, and the obedience of the holy angels compared with what the Son of God has given in His death, even death on a cross?
Martin Luther, from "Treasury of Daily Prayer," page 155.
