863. Noah opened the window of the ark that he had made symbolizes the second state, when religious truth appeared to them. This can be seen from the final words of the last verse (saying that the heads of the mountains appeared) and their meaning; from the symbolism of a window; and from the fact that this is the first moment of light. A window, dealt with above at §655, symbolizes the intellectual side of things and consequently religious truth, which is the same thing.
As for the intellectual realm or the religious truth that the window symbolizes, I must make the same remark as before [§§854, 859]: No religious truth is at all possible unless it develops out of the goodness that goes with love or with charity, just as nothing truly belongs to the intellect unless it rises out of something in the will. If you take away volition, there is no comprehension, as demonstrated several times already [§§112, 585, 590, 628]. So if you take away charity, there is no faith.
But since the human will is undiluted greed, the Lord made a miraculous provision to prevent us from plunging the contents of the intellect — religious truth — into our selfish desires. He divided what belongs to the intellect from our will by the specific means of conscience, which he infuses with charity. Without this miraculous act of providence, no one could ever have been saved.
