1395 Sounding word.... soundboard.... instrument....
April 27, 1940: Book 23
There must be a sounding board, so to speak, if the tone is to sound audibly, and the same applies to the inner voice, which is only ever audible when the human being is receptive to the subtle sound of the divine voice. The instrument.... the human heart.... must first reproduce the sound that the divine master Himself makes resound and that touches the human heart full of intimacy and melodiousness. And the more the instrument is cared for, the sweeter the sound that is elicited from it, and thus every earthly child can hear the sound of the divine word if only it willingly opens its heart and desires to hear the divine voice. And yet it will only very rarely be that God can speak to people in this way. For no-one seriously desires to make use of the divine offer, because the human being does not have the desire to hear what the eternal creator wants to convey to him. And without desire it is again impossible to make divine truth accessible to him. And almost all people are in this situation today. They could hear the word of God, and indeed it can be received by them directly or also through transmission if the human being himself is not able to make his heart receptive. And then the human being is incapable if his will does not cause his heart to serve as a sounding board.... i.e. to listen willingly and joyfully until the voice resounds in the person's heart to the indescribable joy of the listener. For God will speak to everyone who wants to hear His voice; He will place the gift in everyone's heart to receive mental transmissions as well as resounding words and convey them to the brain, where it will first be processed intellectually and thus be conveyed to the person, either as clear thoughts or deeply felt words, which have no other purpose than to bring light and truth to people on earth, insofar as this is requested....
Amen
