Martin Luther on Law and Gospel
“There’s no man living on earth who knows how to distinguish between the law and the gospel. We may think we understand it when we are listening to a sermon, but we’re far from it. Only the Holy Spirit knows this. Even the man Christ was so wanting in understanding when he was in the vineyard that an angel had to console him; though he was a doctor from heaven he was strengthened by the angel. Because I’ve been writing so much and so long about it, you’d think I’d know the distinction, but when a crisis comes I recognize very well that I am far, far from understanding. So God alone should and must be our holy master." – before December 14, 1531
