10. Why is this, I ask of thee, O Lord my God? I see it after a fashion, but I do not know how to express it, unless I say that everything that begins to be and then ceases to be begins and ceases when it is known in thy eternal Reason that it ought to begin or cease--in thy eternal Reason where nothing begins or ceases. And this is thy Word, which is also "the Beginning," because it also speaks to us.(see note 424) Thus, in the gospel, he spoke through the flesh; and this sounded in the outward ears of men so that it might be believed and sought for within, and so that it might be found in the eternal Truth, in which the good and only Master teacheth all his disciples.(see note 425) There, O Lord, I hear thy voice, the voice of one speaking to me, since he who teacheth us speaketh to us. But he that doth not teach us doth not really speak to us even when he speaketh. Yet who is it that teacheth us unless it be the Truth immutable? For even when we are instructed by means of the mutable creation, we are thereby led to the Truth immutable. There we learn truly as we stand and hear him, and we rejoice greatly "because of the bridegroom's voice,"(see note 426) restoring us to the source whence our being comes. And therefore, unless the Beginning remained immutable, there would then not be a place to which we might return when we had wandered away. But when we return from error, it is through our gaining knowledge that we return. In order for us to gain knowledge he teacheth us, since he is the Beginning, and speaketh to us.
