"Where is a self-revelation of this sort achieved? In Life, as its essence, since Life is nothing other than that which reveals itself – not something that might have an added property of self-revealing, but the very fact of self-revealing, self-revelation as such. Everywhere that something like a self-revelation is produced there is Life. Everywhere there is Life, this self-revelation is produced. If, then, the Revelation of God is a self-revelation that owes nothing to the truth of the world, and if we ask where such a self-revelation is achieved, the answer is unequivocal: in Life and in Life alone. Therefore we are in the presence of the first fundamental equation of Christianity: God is Life – he is the essence of Life, or if one prefers, the essence of Life is God. Saying this we already know what God is, but we do not know it through the effect of some knowledge or learning – we do not know it through thought, against the background of the truth of the world. Rather we know it, and we can know it, only in and through Life itself. We can know the essence of God only in God. But this observation is premature."
