Not only the words (vocabula) which the Holy Spirit and Scripture use are divine, but also the phrasing
Martin LutherThe purpose of marriage is not to have pleasure and to be idle but to procreate and bring up children, to support a household. This, of course, is a huge burden full of great cares and toils. But you have been created by God to be a husband or a wife and that you may learn to bear these troubles.
Martin LutherOriginal sin is in us like our beard. We are shaved today and look clean; tomorrow our beard has grown again, nor does it cease growing while we remain on earth. In like manner original sin cannot be extirpated from us; it springs up in us as long as we live.
Martin LutherThere are some of us who think to ourselves, 'If I had only been there! How quick I would have been to help the Baby. I would have washed His linen. How happy I would have been to go with the shepherds to see the Lord lying in the manger!' Why don't we do it now? We have Christ in our neighbor.
Martin Luther
