Thankful to Chris Brauns for pointing out this quote from Martin Luther. I used it in my sermon today.
This is Luther's comment on the Palm Sunday passage in Matthew 21:5 - "Say to the daughter of Zion, ‘Behold, your king is coming to you, humble, and mounted on a donkey, and on a colt, the foal of a beast of burden.’"
He is presented as sheer grace, humility, and goodness, and whoever believes that of him is blessed. Look at him! He rides no stallion, which is a war animal, and he comes not with fearful pomp and power, but sits on a donkey, which is no war animal but which is ready for burdens of work that will help human beings. Thereby he shows that he does not come to terrify people, to drive or oppress them, but to help them, to carry their burdens and take them on himself.
