2207. 'Why did Sarah laugh?' means the thought of rational truth from the affection for it. This is clear from the meaning of 'laughing' or laughter as that affection which is the affection for truth, dealt with above in 2072, and from the representation of 'Sarah' as rational truth, dealt with several times already in this chapter. This question that was asked embodies the Lord's perception that His Rational still possessed within it that which was human.
