20. The Lord will be my present help, and I see that He is present to help me; by your understanding what I say, I see that He is present to help me. For I perceive by these your voices how that you have understood me, and I surely trust that He will still assist us, that you may comprehend the whole. I promised to show you three things which are separately exhibited whose operation is yet inseparable. See then; I did not know what was in thy mind, and thou showedest me by saying, “Memory.” This word, this sound, this expression came forth from thy mind to mine ears. For before that, thou hadst the silent idea of this memory, but thou didst not express it. It was in thee, but it had not yet come to me. But in order that that which was in thee might be passed on to me, thou didst express the very word, that is, “Memory.” I heard it, I heard these three syllables in the word, “Memory.” It is a noun, a word of three syllables, it sounded, and came to my ear, and impressed a certain idea on my mind. The sound has passed away, but the word whereby the idea was conveyed, and the idea itself, remains. But I ask, when thou didst pronounce this word, “Memory,” thou seest certainly that it has reference to the memory only. For the other two things have their own proper names. For one is called “the understanding,” and the other, “the will,” not the “memory,” but that one alone is called “memory.” Nevertheless, whereby didst thou work in order to express this, in order to produce these three syllables? This word which has reference to the memory only, both memory was engaged in producing in thee, that thou mightest retain what thou saidst, and understanding, that thou mightest know what thou retainedst, and will, that thou mightest give expression to what thou knewest. Thanks be to the Lord our God! He hath helped us, both you and me. For I tell you the truth, beloved, that I undertook the examination and explanation of this subject with exceeding fear. For I was afraid lest haply I might gladden the spirit of the more enlarged in mind, and inflict on the slower capacities an afflictive weariness. But now I see both by the attention with which you have heard, and the quickness with which you have understood me, that you have not only caught what I have said, but that you have anticipated my words. Thanks be to the Lord!
