Barth, CD I/2, p. 709:

It is said that H.F.Kohlbrügge one answered the question: When was he converted? by the laconic reply: On Golgotha. This answer, with all its fundamental implications, was not the witty retort of an embarrassed and unconverted man, but the only possible and straightforward answer of a truly converted Christian.  The events of faith in our own life can, in fact, be none other than the birth, passion, death, ascension and resurrection of Jesus Christ, the faith of Abraham, Isaac and Jacob, the exodus from Egypt, its journey through the desert, its entrance into the land of Canaan, the outpouring of the Holy Ghost at Pentecost and the mission of the apostles to the heathen. Every verse in the Bible is virtually a faith-event in my own life...

In comparison with this, what can be the value of the more or less reliable insights which, apart from these testimonies, I may have in myself? Is there a miracle story that I can relate from my own life, which, especially if it is genuine, will not be totally dissolved in this divine miracle story, and which therefore will hardly be worth relating in abstracto? Have I anything to testify about myself which I cannot testify infinitely better if I make my own the simplest ingredient of the Old Testament or the New Testament witness?

Have I experienced anything more important, incisive, serious, contemporary than this, that I have been personally present and have shared in the crossing of Israel through the Red Sea but also in the adoration of the golden calf, in the baptism of Jesus but also in the denial of Peter and the treachery of Judas, that all this has happened to me here and now? If I believe, then this must be the right point of view. If this is the right point of view, what other faith events in my life should I and could I wish to seek? What, then, becomes of the bold assertion with which I claim first this and then that crisis and turning-point, and the gradually my whole life, as a sacred history? And what becomes of the defiant and shrinking doubt and despair about all exalted and exalting moments, and finally about my whole life? However high may rise or however deep may fall the waves of life's events, as they are perceptible to us from within and below, the real movement of my life, the real events in which it is clear to me that in the whole dimension of my existence I belong to God, both at the flood and ebb, are secured from the other side, by the Word of God Himself.
