You probably all know the legend of the rider who crossed the frozen Lake of Constance by night without knowing it. When he reached the opposite shore and was told whence he came, he broke down horrified. This is the human situation when the sky opens and the earth is bright, when we may hear: By grace you have been saved! In such a moment we are like that terrified rider. When we hear this word we involuntarily look back, do we not, asking ourselves: Where have I been? Over an abyss, in mortal danger! What did I do? The most foolish thing I ever attempted! What happened? I was doomed and miraculously escaped and now I am safe! You ask, Do we really live in such danger? Yes, we live on the brink of death. But we have been saved. Look at our Savior, and at our salvation! Look at Jesus Christ on the cross. . . . Do you know for whose sake he is hanging there? For our sake – because of our sin – sharing our captivity – burdened with our suffering! He nails our life to the cross. This is how God had to deal with us. From this darkness he has saved us. He who is not shattered after hearing this news may not yet have grasped the word of God: “By grace you have been saved!”
– Karl Barth, Deliverance to the Captives (quoted by Fleming Rutledge in The Crucifixion)
