From The New Being by Paul Tillich:
Salvation has the nature of a child. As Christendom remembers every year, in the most impressive of festivals, the child Jesus, so salvation, however visible it may be, remains also invisible. He who wants a salvation which is only visible cannot see the divine child in the manger as he cannot see the divinity of the Man on the Cross and the paradoxical way of all divine acting. Salvation is a child and when it grows up it is crucified. Only he who can see power under weakness, the whole under the fragment, victory under defeat, glory under suffering, innocence under guilt, sanctity under sin, life under death can say: Mine eyes have seen thy salvation.
